  • Vijayanagara’s architecture was influenced by the Sultanate of Bijapur and Golconda example their elephant stables.

Mughal rulers were particularly skilled in adapting regional architectural styles in the construction of their own buildings.

  • The Mughals liked this “Bangla dome” so much that they used it in their architecture.
  • The impact of other regions was also evident.
  • In Akbars capital at Fatehpur Sikri many of the buildings bear the impact of the architectural styles of Gujarat and Malwa.

Mughal Traditions of Succession

Question 1.
Describe the Mughal traditions of succession.

  • Mother of Shah Jahan: A Rathor Princess, daughter of a Rajput, the ruler of Marwar (Jodhpur).

Question 2.
Give an account of the Mughal relations with other rulers.
Answer:
Mughal relations with other rulers:

  • Mughal rulers campaigned constantly against rulers who refused to accept their authority.
  • The Mughals became powerful only when many other rulers joined them voluntarily.
  • The Rajputs are a good example of this.
  • Many of them married their daughters into Mughal families.
  • Then they received high positions.
  • But many resisted this as well.
  • The Sisodiya Rajputs refused to accept Mughal authority for a long time.
  • After their defeat, they were honourably treated by the Mughals.
  • They were given their lands (watan) back as assignments (watan jagir).
  • The careful balance between defeating opponent kings and chieftains enabled the Mughals to expand their kingdoms.
  • But it was difficult to keep this balance all the time.
  • Aurangzeb insulted Shivaji when he came to accept Mughal authority.
  • The consequence of this insult was that the Aurangzeb empire fell down like a pack of playcards.

Mansabdars and Jagirdars

Question 1.
Who all formed the Mughal nobility?
Answer:

  • With the expansion of Mughal empire, the Mughals recruited diverse bodies of people.
  • From a small nucleus of Turkish nobles (Turanis) they expanded to include Iranians, Indian Muslims, Afghans, Rajputs, Marathas and other groups.
  • Those who joined Mughal service were enrolled as mansabdars.

Question 2.
What were the duties of the Mansabdars?
Answer:
Mansabdars and their duties:

  • The term mansabdar refers to an individual who holds a mansab (a position or rank).
  • It was a grading system used by the Mughals to fix (t) rank, (ii) salary and (iii) military responsibilities.
  • Rank and salary were determined by a numerical value called zat. The higher the zat, the more prestigious was the noble’s position in court and the larger his salary,
  • The mansabdar had military responsibilities.
  • It required him to maintain a specified number of sawar or cavalrymen.
  • The mansabdar brought his cavalrymen for review, got them registered, their horses branded and then received money to pay them as salary.

Question 3.
How did the Mansabdars get their salaries?
Answer:
Mansabdars received their salaries as revenue assignments called jagirs.

  • They were like iqtas.
  • Most of the mansabdars did not actually reside in or administer their jagirs.
  • They only had rights to the revenue of their assignments which was collected for them by their servants.
  • Mansabdars themselves served in some other parts of the country.

Question 4.
Give an account of ranking on the basis of zat.
Answer:
Zat ranking:

  • Nobles with a zat of 5,000 were ranked higher than those of 1,000.
  • In Akbar’s reign there were 29 mansabdars with a rank of 5,000 zat.
  • By Aurangzeb’s reign the number of mansabdars had.increased to 79*.
  • This had meant more expenditure for the state.

Question 5.
Describe Jagirdars and their duties.
Answer:
Jagirdars and their duties

  • In Akbar’s reign these jagirs were carefully assessed so that their revenues were roughly equal to the salary of the mansabdar.
  • By Aurangzeb’s reign situation changed and the actual revenue collected was often less than the granted sum.
  • There was also a huge increase in the number of mansabdars which meant a long wait before they received a jagir.
  • These and other factors created a shortage in the number of jagirs. Hence, many jagirdars tried to extract as much revenue as possible while they had a jagir.
  • Aurangzeb was unable to control these developments in the last years of his reign, so the peasantry suffered tremendously.

Zabt and Zamindars

Question 1.
Who were Zamindars? What were their duties?
Answer:
The Zamindars

  • The main source of income of the Mughal rulers was tax on the produce of the peasantry.
  • In most places, peasants paid taxes through the rural elites.
  • The rural elite was the headman or the local chieftain.
  • The Mughals used the term—zamindars—to describe all intermediaries, whether they were local headmen of villages or powerful chieftains.

Question 2.
What was ‘Zabt’?
Answer:

  • Akbar’s revenue minister, Todarmal, carried out a careful survey of crop yields, prices and areas cultivated for a ten-year period, 1570-1580.
  • On the basis of this data, tax was fixed on each crop in cash.
  • Each province was divided into revenue circles with its own schedule of revenue rates for individual crops.
  • This revenue system was known as zabt.

Question 3.
What was the role of Zamindars?
Answer:
Zabt was prevalent in those areas where Mughal administrators could survey the land and keep very careful accounts. This was not possible in provinces like Gujarat and Bengal.

  • In some areas the zamindars exercised a great deal of power.
  • The exploitation by Mughal administrators could drive them to rebellion.
  • Sometimes zamindars and peasants of the same caste allied in rebelling against Mughal authority.
  • These peasant revolts challenged the stability of the Mughal Empire from the end of the seventeenth century.

  • These discussions took place in Ibadat Khana. These were about social and religious customs.
  • These interactions made him realise that religious scholars are bigots. They emphasize rituals and dogma.
  • Their teachings create divisions in society. This led to the idea of Sulh-i-Kul or ‘Universal peace’.

Question 6.
What is Sulh-i kul or universal peace?
Answer:

  • The idea of tolerance did not discriminate between people of different religions r in his realm.
  • It focused on a system of ethics – honesty, justice, peace – that was universally applicable.

  • This expenditure benefited the artisans and peasantry who supplied them with goods and produce.
  • But the scale of revenue collection left very little for investment in the hands of the primary producers, the peasants and the artisans.
  • The poorest among them lived from hand to mouth.
  • They could not consider investing in additional resources like tools and supplies to increase productivity.
  • The wealthier peasantry and artisanal groups, the merchants and bankers profited in this type of economy.

Question 3.
What happened politically with the gradual decline of Mughal rule?
Answer:

  • The enormous wealth and resources commanded by the Mughal elite made them an extremely powerful group of people in the late seventeenth century.
  • With slow decline of the authority of the Mughal emperor, his servants emerged as powerful centres of power in the regions.
  • They constituted new dynasties and held command of provinces like Hyderabad and Awadh.
  • Although they continued to recognise the Mughal emperor in Delhi as their master, by the eighteenth century the provinces of the empire had consolidated their independent political identities.

Question 1.
What is the difference between the two maps of India made in 1154 and 1720?
Answer:
Al-Idrisi an Arab cartographer made a map in 1154 CE. French cartographer made the map of same area in 1720’s. The two had certain differences:

  • Al-Idrisi’s map had south India in place of north India. Sri Lanka was at the top.
  • Place names are marked in Arabic. Kanauj is spelt as Qanauj and is shown in Uttar Pradesh.
  • French cartographer’s map was made about 600 years later. There were many changes by the time.
  • This map is more familiar. Coastal areas are more detailed.
  • This map was used by the European sailors and merchants on their voyages.

Question 2.
What precautions historians should follow while reading the maps?
Answer:
Historians reading the maps, documents or texts from the past should be sensitive about the contends. They should keep in mind the different historical background. Equally important is the fact that the science of cartography differ from period to period.

New and Old Terminologies

Question 1.
Does the information given in historical records change over the years?
Answer:
Historical records exists in a variety of languages. These languages changed over time. For example, Medieval Persian is different from modem Persian in grammar, vocabulary and even meaning of words.

Question 2.
How has the term ‘Hindustan’ changed over the centimes?
Answer:
The meaning of the term ‘Hindustan’ has changed over the centuries in the following manner:

  • In the thirteenth century Minhaj-i-Siraj used the term ‘Hindustan’. He meant areas of Punjab, Haryana and the lands between Ganga and Yamuna. He used this term in a political sense that were a part of the dominions of the Delhi Sultanate. The term never included South India.
  • In the sixteenth century poet Babur used the term ‘Hindustan’ to describe the geography, the fauna and the culture of the inhabitants of the subcontinent.
  • In fourteenth century poet Amir Khusrau used the term ‘Hind’ in the same sense as Babur did in the sixteenth century.
  • ‘Hindustan’ did not carry the political and national meanings as the term ‘India’ does today.

Question 3.
How are historians to be careful about the term they use as they go on changing with time?
Answer:
Historians are to be careful about the terms they use because their meanings go on changing with change in time.

Example:
We take a simple term ‘Foreigner’.

  • It is used today to mean a person who is not an Indian.
  • In the medieval period a ‘foreigner’ was any stranger who was not a part of that society or culture.
  • In Hindi the term pardesi is used to describe such a person and in persian, ajnabi.
  • A city-dweller regarded a forest-dweller as a ‘foreigner’ but two peasants living in the same village were not foreigners to each other, though they belonged to different religions or caste backgrounds.

Historians and Their Sources

Question 1.
What are the sources used by the historians to study the past?
Answer:
Historians use variety of sources to study the past. It depends upon the period of their study and nature of study. They use those resources that provide some continuity. Historians still rely on coins, inscriptions, architecture and textual records.
There appeared some discontinuity as well. The variety of textual records increased from 700 to 1750. They slowly replaced other types of available sources. During this period paper gradually became cheaper and easily available.

Question 2.
What was the result of easy availability of paper in the 14th century?
Answer:

  • People used paper to write holy texts, chronicles of rulers, letters and teachings of saints, petitions and judicial records and in preparing accounts and taxes.
  • Manuscripts were collected by wealthy people, rulers, monasteries and temples.
  • They were placed in libraries and archives.
  • They provided a lot of detailed information to historians.
  • Manuscripts were difficult to use.

Question 3.
What was the result of non-availability of printing press in the 13th and 14th centuries?
Answer:
Historians faced a lot of difficulties while using manuscripts because:

  • There was no printing press in the 13th and 14th centuries. Scribes in those days made manuscripts by hand.
  • To copy was not an easy exercise. Scribes could not read the handwriting of the other writers.
  • They were forced to guess. So there were small but significant differences in the copy of the scribed.
  • These small words or sentences here and there grew over centuries of copying.
  • The manuscripts of the same text became a great extent different from the original.

Question 4.
Describe the problem of dearth of original manuscripts of the authors.
Answer:
There is a serious problem because we rarely find the original manuscripts of the authors today.

  • We are totally dependent upon the copies made by later scribes.
  • The result is that historians have to read different manuscript versions of the same text to guess what the author had originally written.
  • On several occasions authors revised their chronicles at different times.
  • The fourteenth century chronicler Ziyauddin Barani wrote his chronicle first in 1356 and another version came two years later.
  • The two versions differ from each other.
  • Historians did not know about the existence of the first version until 1960s.
  • It remained lost in large library collections.

New Social and Political Groups

Question 1.
How is the study of the thousand years between 700 and 1750 a huge challenge to historians?
Answer:
The study of the thousand years between 700 and 1750 is a huge challenge to historians because of

  • Scale and variety of developments that occurred during this period.
  • At various moments in this period new technologies made their appearance.
  • All the innovations, new technologies and crops came along with people. They brought other ideas with them as well.
  • In this way, this was a period of economic, political, social and cultural changes.

Question 2.
What were the new technological advancement between 700 and 1750?
Answer:
Some of the technological changes associated with this period are:

  • Persian wheel in irrigation.
  • Spinning wheel.
  • Fire-arms in combat.

Question 3.
Which are the; other new things happening during this period?
Answer:
During this period many things were happening like:

  • New foods and beverages like potatoes, com, chillies, tea and coffee arrived in the subcontinent.
  • Groups of people travelled long distances in search of new opportunities.
  • The subcontinent held immense wealth and many possibilities for people to get a fortune.

Question 4.
What does the word ‘Rajputs’ stand for?
Answer:
‘Rajputs’ word has been derived from Rajaputra’ the son of a ruler. Between the eighth and the fourteenth centuries the term was applied more generally to a body of warriors who claimed Kshatriya caste status. The term included not just rulers and chieftains but also soldiers and commanders.

They served in the armies of different monarchs all over the subcontinent. A chivalric code of conduct, including extreme valour and a great sense of loyalty were the qualities attributed to Rajputs by their poets and bards.

Question 5.
Name the various groups that became important between 700-1750.
Answer:
The various groups that became politically important between 700 and 1750 were Rajputs, Sikhs, Marathas, Jats, Ahoms, Kayasthas etc.

Question 6.
What nugor changes occurred between 700 and 1750 A.D.?
Answer:

  • Throughout the period between 700 and 1750 there was a gradual clearing of forests and the extension of agriculture. This was a change faster and more complete in some areas than in others.
  • Changes in their habitat forced many forest-dwellers to migrate.
  •  Others started tilling the land and became peasants.

Regional markets, chieftains, priests, monasteries and temples began to influence them.

  • They became part of large complex societies.
  • They were required to’ pay taxes and offer goods and services to local lords.

As a result, significant economic and social differences emerged among the peasants.

  • Some possessed more productive land.
  • Others kept cattle,
  • Yet others combined artisanal work with agricultural activity during the lean season.

Question 7.
How were the people grouped into jatis?
Answer:
As society became more uneven people were grouped into jatis or sub-castes and ranked on the basis of their backgrounds and their occupations.
Ranks were not fixed permanently:

  • They varied according to the power, influence and resources controlled by members of the jati.
  • The status of the same jati could vary from area to area.

Question 8.
How were the jatis regulated?
Answer:
The affairs of jatis were regulated in the following way:

  • Jatis formed their own rules and regulations.
  • There was an assembly of elders called jati panchayat.
  • It enforced the rules and regulations.
  • Jatis were also directed to follow the rules of the village.
  • Several villages were governed by a chieftain.

Question 9.
What is the contribution of the medieval period to the Indian history?
Answer:
Medieval period (due to its contribution) is considered very important in the Indian history. We can mention its contribution in following points:

  1. Many modem languages, which we speak nowadays in India, developed at this time.
  2. Some of the food items we eat and the clothes we wear became popular during this age.
  3. The history of many of our current religious faiths (such as Islam, Sikhism, etc.) can be traced back to this period.

Region and Empire

Question 1.
What was the extent of Balban’s empire?
Answer:
Ghiyasuddin Balban (1266-1287) claimed himself to be the ruler of vast empire. It stretched from Bengal (Gauda) in the east to Ghazni (Gajjana) in Afghanistan in the west. It included all of south India.

People from different regions-Gauda, Andhra, Kerala, Karnataka, Maharashtra and Gujarat fled before his armies came. Historians regard this as exaggerated claims. It is a question of debate why rulers kept claiming about their conquests.

Question 2.
Explain the features of regions by 700 A.D.
Answer:

  • By 700 A.D. regions already possessed distinct geographical dimensions.
  • They had their own language and cultural characteristics.
  • They were also associated with specific ruling dynasties.
  • Thfere was considerable conflict between these states.
  • Occasionally dynasties like the Cholas, Khiljis, Tughluqs and Mughals were able to build an empire that was pan-regional, covering various regions. These empires were not equally stable or successful.

Question 3.
What did the decline of the Mughal Empire lead to in the 18th century?
Answer:

  • When the Mughal Empire declined in the eighteenth century, it led to the re-emergence of regional states.
  • Years of imperial, pan-regional rule had altered the character of the regions.
  • Across most of the subcontinent the regions were left with the legacies of the big and small states that ruled over them.
  • This was clear in the emergence of many distinct and shared traditions: in the way of governance, the management of the economy, elite cultures, and language.
  • Through the thousand years between 700 and 1750 A.D. the character of the different regions did not grow in isolation.
  • They felt the impact of larger pan-regional forces of integration without losing their own character.

Old and New Religions

Question 1.
What developments have taken place in religious traditions during this period?
Answer:
During the thousand years there were many developments in religious traditions. People’s belief in divine was personal and collective. Collective belief was in supernatural agency-religion. It was connected to social and economic aspects of local communities. With the changes in social aspects the religious beliefs also changed.

Question 2.
Describe the major development in Hindu religious traditions during the period 700 to 1750 A.D.
Answer:

  • The thousand years of history between 700 and 1750 A.D. witnessed major developments in religious traditions.
  • It was during this period that important changes occurred in Hinduism.
  •  The worship of new deities.
  • The construction of temples by royalty.
  • Their knowledge of Sanskrit texts earned the Brahmanas a lot of respect in society and support of new rulers or patrons searching for prestige.
  • One of the major developments was the emergence of the idea of Bhakti.
  • It was of a loving, personal deity that devotees could reach without the aid of priests or elaborate rituals.

Question 3.
Which new religion came to India during the period between 700 and 1750 A.D.?
Answer:
The period between 700 and 1750 A.D. was the period when new religions appeared in the subcontinent.
Merchants and migrants first brought the teachings of the holy Quran to India in the seventh century. Many rulers were patrons of Islam, Jurists and theologians.

  • Muslims regard the Quran as their holy book.
  • They accept the sovereignty of the one God or Allah.
  • Islam was interpreted in a variety of ways by its followers:
  • Shia Muslims believed that the prophet’s son-in-law, Ali, was the legitimate leader of the Muslim community.
  • Sunni Muslims accepted the authority of the early leaders (Khalifas) of the community, and the succeeding Khalifas.
  • There were other important differences between the various schools of law and in theology and mystic traditions.
  • The schools of law are Hanafi and Shafi’i, mainly in India.

Thinking about Time and Historical Periods

Question 1.
How do historians divide the history of India into three periods? What are the drawbacks of this division?
Answer:
According to historians time reflects changes in social and economic organisation, in transformation of ideas and beliefs. They do not see it as clock or calender.

The study of time is made somewhat easier by dividing the past into large segments. They are called periods. The periods possess shared characteristics.

In the middle of the nineteenth century British historians divided the history of India into three periods.

  • They are ‘Hindu’, ‘Muslim’ and ‘British’.
  • This division was based on the idea that the religion of rulers was the only important historical change, and that there were no other significant developments in result of the economy, society or culture.
  • Such a division also ignored the rich diversity of the subcontinent. Few historians follow this periodisation today. Most look to economic and social factors to characterise the major elements of different moments of the past.

Question 2.
What is included in the study of history?
Answer:
Early history included study of different societies—hunter gatherers, early farmers, people in towns and villages, early empires and kingdoms.

The medieval history is more about peasant societies, rise of regional or imperial states, the growth of Hinduism and Islam as religions. It also includes the arrival of European trading companies.

Question 3.
Why there is a problem in studying a long period of history as one unit?
Answer:
Thousand years of history is full of change. 16th and 17th centuries were different from 8th or 11th centuries. Therefore entire period cannot be described as one unit.

Modem period is associated with material and intellectual progress. But, this does not mean the medieval period had no development at all. All this creates confusion, hence periodisation was required.

During these thousand years the societies of subcontinent were developed and economies too prospered. This attracted interest of European trading companies.

Wastewater Story Class 7 Science Extra Questions Short Answer Type Questions

Question 1.
Open drain is a big concern now-a-days. Justify.
Answer:
Open drain is a big concern for the society now-a-days because they create unhygienic conditions. It provides favourable conditions to flies, mosquitoes and other insects to breed and spread a number of diseases.

Question 2.
Explain, how sewage is disposed of in an aeroplane.
Answer:
Aeroplanes have their closed waste sewage tanks in them, which suck the wastewater and collect it in their tanks.
Once the aeroplane lands on the ground, the crew disposed of the sewage properly into airport sewage facility.

Question 3.
Sewage also contains some nutrients Comment.
Answer:
Sewage is a complex mixture which contains suspended solids, organic and inorganic impurities, nutrients, saprotrophic and disease causing bacteria and other microbes.
The nutrients present in sewage are phosphorus and nitrogen.

Question 4.
Suggest two alternative arrangements for sewage disposal where there is no sewerage system.
Answer:
The two alternative arrangements for sewage disposal, where there is no sewerage system are as below

  • Septic tanks
  • Composting pits.

Question 5.
Recall and enlist some better house keeping practices.
Answer:
We must minimise and manage waste at our houses before its disposal in the following manner:

  • Cooking oil and fats should not be thrown down the drain. They can harden and block the pipes. In an open drain the fats clog the soil pores reducing its effectiveness in filtering water. Throw oil and fats in the dustbin.
  • Used tealeaves, solid food remains, soft toys, cotton, sanitary towels, etc., should also be thrown in the dustbin. These wastes choke the drains. They do not allow free flow of oxygen. This hampers the degradation process.
  • The chemicals like paints, solvents, insecticides, medicines and motor oils should 1 State the role of screen bars in wastewater treatments, not be thrown in drains as they kill helpful 2 Chlorination makes water fit for human consumption. How? microbes which digest the organic waste.

Question 6.
Water in a river is cleaned naturally. Do you agree? Think and explain. [HOTS]
Answer:
Yes, river water is cleaned naturally by a process that is similar to wastewater treatment plant.
As muddy water when flows through grass or weeds on its way to a stream, mud and solid particles get filtered out. At the bottom of a lake or stream, microorganism brings chemical changes in the water. The natural filtration process removes pollution from the roundwater throughout the process making it clean and fit for drinking.

Question 7.
The terms sewage, sewers and sewerage are interlinked with each other. Can you explain, how? [NCERT Exemplar]
Answer:
The terms like sewage, sewers and sewerage are interlinked with each other because sewage is a mixture of wastewater coming out of homes and other places. Sewers are pipes which carry sewage and sewerage is a network of sewage carrying pipes.

Question 8.
Describe onsite disposal systems.
Answer:
Some organisations offer hygienic onsite human waste disposal technology. These toilets do not require scavenging. Excreta from the toilet seats flow through covered drains into a biogas plant. The biogas produced is used as a source of energy.

Question 9.

Wastewater Story Class 7 Science Extra Questions Long Answer Type Questions

Question 1.
Explain the different types of inorganic and organic impurities generally present in sewage.
Answer:
It is wastewater released by homes, industries agricultural fields and other human activities. It also includes rainwater that has run down the street during a storm or heavy rain and it is a liquid waste. Most of its water has dissolved and suspended impurities called contaminants.
Composition of Sewage
The following components make the sewage:

  • The organic impurities present in sewage are human faeces, animal wastes (like animal dung), urea (as urine), oil, fruits and vegetable wastes, pesticides, herbicides, etc.
  • The inorganic impurities present in sewage are nitrates, phosphates and metals.
  • The nutrients present in sewage are nitrogen and phosphorus.
  • The bacteria present in sewage include those bacteria which cause water-borne diseases such as cholera and typhoid.
  • The other microbes present in sewage are Protozoa which cause a water-borne disease called dysentery.

Question 2.
Describe septic tank. How does it function?
Answer:
Low cost outside sewage disposal system have been developed to take care of places where there is no sewage system, e.g. rural areas, isolated buildings. These are described below:
(i) Septic tanks Septic tank is a low cost onsite sewage disposal system. Septic tanks are suitable where there is no sewerage made. These tanks need cleaning every four to six months.

A septic tank usually consists of a big, covered underground tank made of concrete having an inlet pipe at one end and on outlet pipe at the other end. The toilet seat is connected to the inlet pipe of the septic tank. The human excreta from the toilet seat enters into the septic tank through the inlet pipe. The solid part of excreta keeps on collecting at the bottom of the septic tank in the form of a sludge whereas watery waste remains above it.

The anaerobic bacteria breakdown most of the solid organic matter present in human excreta due to which the volume of solid waste is reduced too much. The digested solid waste keeps on depositing at the bottom of septic tank. The watery waste is also cleaned by anaerobic bacteria. The excess water goes out of the septic tank through the outlet pipe and get absorbed in soil.

(ii) Composting pits These are self sustained human waste disposal units which is not connected to a sewer line or a septic tank. A composting toilet breaks down and dehydrate human waste to compost.

(iii) Chemical toilets These toilets have limited storage capacity for human waste and need to be emptied periodically. These are the toilets which use chemically treated reservoir located just below the toilet seats. The chemicals reduce the foul smell coming out of human excrete and carry out partial disinfection of human waste.

Question 3.
Discuss vermi-processing toilets. Name the useful product obtained from such toilets.
Answer:
In the vermi-processing toilet, the human excreta is treated by earthworms in a pit. The earthworms gradually eat up all the organic matter present in human excreta, decompose it and pass out from their body in the form of warm casting (also called vermi cakes).
The useful product obtained from a vermi-processing toilet is vermi cakes which is kind of high quality manure.

Forests: Our Lifeline Class 7 Science Extra Questions Short Answer Type Questions

Question 1.
Forests are valuable resources. Explain.
Answer:
Forest products play vital role in socio-economic development. We get food (cereals, pulses, fruits), fire wood, fibre, construction material, industrial products (tannins, lubricants, dyes, resins, perfumes) and products of medicinal importance. It is also the home of diverse wildlife which maintains the ecosystem. Thus, forests are valuable resources.

Question 2.
Plants help in maintaining O2-CO2 cycle. Explain it in the light of photosynthesis and respiration.
Answer:
Photosynthesis is the process during which CO2 is used by the plants and O2 is released as a products. This O2 is used by the animals for their respiration and CO2 is released during it which is again used for photosynthesis by plants. In this way, O2-CO2 cycle is balanced by plants.

Question 3.
Forests are called green lungs. Why?
Answer:
The forests provide us oxygen to breathe. If we rapidly cutting down forests means we are cutting down the oxygen supply to us. That is why they are called green lungs.

Question 4.
Two friends shared their experiences of their vacation trip to two different forests. Do you think they would have seen the same type of plants and animals during their respective trips? Give reason. [HOTS]
Answer:
No, they would not have seen the same type of plants and animals. This is so because climatic conditions in the two forests would vary leading to variations in the types of plants and animals.

Question 5.
Write differences between decomposers and scavengers.
Answer:
Difference between decomposers and scavengers is

DecomposerScavenger
These are the microbes which break dead organic matter into simple molecules to be used by plants again.These animals eat the body of dead animals and are called cleaning agent of forests, e.g. jackal, fox, vultures, etc.

Question 6.
What would happen if forests disappear?

Question 7.
Plants are known as the producers of a food chain. Give reason.
Answer:
Plants are known as the producers of a food chain. It is because green plants (autotrophs) make their own food from carbon dioxide and water in the presence of sunlight and chlorophyll by a process called photosynthesis and provide food to all living organisms which live in the forest.

Question 8.
Life would be impossible without plants. Explain, how.
Answer:
All green plants are producers. They make food by the process of photosynthesis using water C02 and sunlight. All forms of animals depend on plants for food. So, if there no plants, no food will be there. Plants are give oxygen also during photosynthesis, and there would be no oxygen in absence of plant. These two basic needs make plants important for us and we cannot think of life without plants.

Question 9.
Y and Z are two types of organism which are found in the forests. Y eats up dead animals while Z breakdown the body of the dead animals into simpler substances.
(a) What is the general name of organism Y?
(b) Write one example of Y type organism.
(c) What is general name of organism Z?
(d) Write one example of Z type organism. (HOTS]
Answer:
(a) Scavenger
(b) Vulture
(c) Decomposers
(d) Fungi (mushroom)

Question 10.
What happens when an animal dies in the forest?
Answer:
The body of the dead animal is eaten up by scavengers like vultures, jackals, hyanas, etc.
These animals do the functions of cleaning in the forest. This also shows that nothing goes waste in the forests.

Question 11 .
Give any four factors which are responsible for the destruction of forests. [NCERT Exemplar)
Answer:
The four factors which are responsible for the destruction of forests are

  • Construction of roads.
  • Construction of buildings.
  • Industrial development.
  • Increasing demand of wood.

Question 12.
Is it possible to construct a food chain without a producer? State the reason to support your answer.
Answer:
No, in any food chain, producers are always at the beginning. It is the producer which provides food to all living organisms. In a food chain, if producer is absent, then there will be no flow of energy. So, we can say that it is not possible to construct a food chain without a producer.

Question 13.
How can a pipal sapling would have grown on a side wall of some old buildings?
Answer:
Animals disperse the seeds of certain plants with the help of their droppings. Therefore, pipal seed would have come to the wall by a bird dropping . On coming in contact with water and suitable nutrient medium, it would have grown into pipal sapling.

Question 14.
If one component of the forest is removed, what would be its affect on the ecosystem?
Answer:
Every component of forest depend on other. If we remove one, the other will be affected, e.g. if we remove top carnivores (lion/tiger) in a forest, herbivores will increase and if they increase they will end up eating all plants, so ecosystem will get disturbed.

Question 15.
State the role of scavengers in cleaning of our environment.
Answer:
Scavengers eat the dead animals and act as the cleaning agents of our environment. Some of these animals (scavengers) are vultures, crows, jackals, hyena, some insects, etc.

Question 16.
Crown is different from canopy. Explain how.
Answer:
The part of the tree with branches is known as the crown. When the crown of tall trees in the forests forms a roof-like covering over the others plants, it is known as a canopy.

Question 17.
“You conserve forest, you conserve soil”. Do you agree? Justify. [HOTS]
Answer:
Yes, forests bind soil with root and prevent soil erosion. They also maintain fertility of soil and check So, it can be said that conserving forest results in conservation of soil.

Question 18.
Deforestation can increase the earth’s temperature. Is it true? Give reason.
Answer:
Yes, if there are no tress and plants, there will be no photosynthesis. So, no CO2 of the atmosphere will be used. This will increase the level of CO2, resulting in the increase of earth’s temperature.

Question 19.
Explain how root system of plants help in the prevention of flood?
Answer:
The root system helps water to seep down in the ground. It helps to maintain the water table throughout the year. Roots of trees normally bind the soil together and stop the erosion of soil.

Question 20.
Sketch a diagram to show how plants maintain the balance between carbon dioxide and oxygen in the atmosphere?
Answer:
Forests Our Lifeline Class 7 Extra Questions Science Chapter 17 1

Forests: Our Lifeline Class 7 Science Extra Questions Long Answer Type Questions

Question 1.
People say that nothing goes waste in a forest. Can you explain how? [NCERT Exemplar; HOTS]
Answer:
Nothing goes waste in a forest because of the following reasons

  • Dry leaves and remains of dead animals are converted to a dark coloured substance called humus. This provides nutrients to the plants.
  • Dead animals become food for vultures, crows, jackals and insects.
  • Broken branches of trees are used as fuel by the people living in the vicinity of the forest.

Question 2.
“Forest is a dynamic entity, full of life and vitality”. Explain briefly. [HOTS]
Answer:
Forests harbour great variety of plants and animals. Plants provide food to herbivores. Larger number of herbivores means increased availability of food for a variety of carnivores. Wide variety of animals helps forest to regenerate.

Decomposers and scavengers are cleaning agents. So, every entity in the forest plays a key and vital role making it a dynamic living entity, full of life and vitality.

Question 3.
Write the major steps by which we can conserve the forest.
Answer:
Forests maintain balance in nature. There conservation is the need of the hour. We should take the following steps to conserve the forests

(i) Planned harvesting An efficient way to get wood from forests for our requirements is to cut only some of the trees in an area. The uncut trees prevent erosion. Fruits of these trees produce seeds so that new trees can grow. This way the forest cover is maintained.

(ii) Afforestation This is the practice of renewing a forest by planting seedlings or small trees. These days, in our country, planned afforestation is being done not only by the government but also by private organisations for commercial purposes. Selective cutting of trees in these plantations provides wood for construction and also keeps the forest cover intact.

(iii) Protection from fire Huge forest areas are destroyed by fire every year. Fire may occur due to the carelessness of people or due to lightning during a storm or by friction between dry stems and dry branches of trees.
Forest fires are controlled by spraying fire extinguishing solutions from aircrafts or by changing the direction of wind by using strong blowers.

Question 4.
Figure shows a part of a forest.
Forests Our Lifeline Class 7 Extra Questions Science Chapter 17 2
Write any three activities going on in the forest on the basis of this figure. [NCERT Exemplar]
Answer:
The three activities going on in the forest on the basis of the given figure are

  • Oxygen is given out by plant leaves.
  • Carbon dioxide is consumed by the plants to prepare their food by the process of photosynthesis.
  • Nutrients are being added to the soil by the action of decomposers.

Question 5.
Cycling of papers help in the conservation of the forests. Justify.
Answer:
The papers are made from wood pulp. We derive wood by cutting down trees. If we recycling existing quantity of paper in the market and will not let it decompose, we can stop cutting of forest trees for new raw materials required for paper making.
It takes years to grow a tree and cutting a tree takes only few minutes.
So, we should give a serious thought before cutting a single tree even and should encourage recycling of papers every where in our country and in the world.

Question 6.
Sachin lives in a village, this village is surrounded by a forest. One day he noticed that in nearby pond sedimentation is increased so much that water has become muddy, streams are drying up. There is scarcity of fuel wood. He soon realised that he has to raise the issue of forest protection from cutting down trees, etc. Soon he involved the nearby village people and made an organisation to take an initiative.

Water: A Precious Resource Class 7 Science Extra Questions Short Answer Type Questions

Question 1.
Explain how the traditional use of groundwater is different from the present use.
Answer:
Traditionally in ancient times, people made bawris to collect rainwater in the old buildings. We still use these structures and are reviving them to harness rainwater.

Question 2.
Planting trees help groundwater conservation. Explain how.
Answer:
Plants lose water in the form of water vapour by the process of transpiration. So, forests contribute a lot of water vapours formation which make clouds.
Thus, plants help to revive water cycle.

Question 3.
List the reasons for lowering of water table in cities.
Answer:
Water drawn from underground water gets replenished by seepage of rainwater. The water table does not get affected as long as we draw the same amount of water as is replenished by natural resources like rain.

However, there are number of factors which cause depletion of water table at a very fast rate which is really a matter of concern for everyone of us. Increase in population, industrial and agricultural activities are some common factors affecting water table. Scanty rainfall, deforestation and decrease in the effective area for seepage of water may also deplete the water table.

  • Petrochemical industries, e.g. petroleum and different fuels.
  • Oil industries.

All the above industries release pollutants such as asbestos, lead, mercury, nitrates, sulphur, etc in different rivers, lakes and ponds which are polluting the water and hence is responsible for depletion of water table.

Question 10.
Mention three causes of water scarcity in our country.
Answer:
The three causes of water scarcity in our country are

  • Rapid urbanisation.
  • Increased number of industries.
  • Population explosion.

Question 11.
Certain pattern of the rainfall in our country leads to scarcity of water. Explain that pattern. Which part of the country gets rainfall twice a year?
Answer:
We face shortage of water mainly because water is not evenly distributed by the nature on the earth. Some places such as North East India get so much rains, so that it gets flooded almost every year. On the other hand, Thar desert in Rajasthan may get rains rarely in the monsoon season. This uneven pattern of rains causes water scarcity in India at some places.

Question 12.
A number of problems can be faced due to shortage of water. List some of them.

Question 14.
Some definitions are given which can be corrected by changing one word. Correct them.
(a) Aquifer is groundwater stored between layers of hard rock above the water table.
(b) The process of evaporation of water in the ground is called infiltration.
(c) The evaporation of water from oceans and its arrival back into oceans is called vapour cycle. (NCERT Exemplar]
Answer:
(a) Aquifer is groundwater stored between layers of hard rock below the water table.
(b) The process of seeping of water in the ground is called infiltration.
(c) The evaporation of water from oceans and its arrival back into oceans is called water cycle.

Question 15.
Deforestation can be considered as a reason for depletion of the water table. Comment.
Answer:
Large scale deforestation has occurred to accommodate the growing population, to grow food for them and to provide space for industries. Vegetation slows down the flow of rainwater on land and increases the absorption of water by the soil.
Cutting down of trees and destroying vegetation, therefore interferes with the natural process by which seeping takes place and the groundwater is recharged.
It finally results in the depletion of the water table.

Question 16.
Give the main causes of water scarcity in our country.
Answer:
The main causes of water scarcity in our country are

  • Rapid urbanisation.
  • Increased number of industries.
  • Population explosion.

Water: A Precious Resource Class 7 Science Extra Questions Long Answer Type Questions

Question 1.

(b) Sachin is planning to harvest rainwater.
(c) Sachin will educate people to use water judicially in the following way
(i) Use mug for brushing, shaving and bathing.
(ii) Water plants with drip irrigation.
(iii) Use and reuse water in home activities.

Question 2.
Two figures ‘a’ and ‘b’ are given below. Both are revealing two different human activities which are the cause of depletion of water table. Identify the two acts and explain how are these causing the depletion of water resource. [HOTS]
Water A Precious Resource Class 7 Extra Questions Science Chapter 16 2
Answer:
(a) Large scale construction
(b) Deforestation
Large scale construction It is main cause of water table lowering because it utilises large amount of water at the time of construction. Most of the time, it is digged water table.

Secondary, when ground surface becomes cemented. It does not allow seepage of rainwater into deeper layers, so rainwater goes waste as run off water and cannot replenish the water table of that particular place.

Deforestation Plants transfer huge amount of water in the form of water vapours. So, when forests are cut down, we interrupt in the process of water cycle of that area. So, no rain occurs at that place and it gradually turns into desert area.

Question 3.
Shishir returned from school and found his mother busy in the kitchen. He noticed that she is making his favourite dosa. Shishir rushed to his mother as he was feeling hungry and found that the tap in the kitchen was leaking. He told his mother to replace it as leaking taps lead to the wastage of water. His mother smiled and ensured him to do the same.
(a) What is water management?
(b) Why should we save water?
(c) What values are shown by Shishir? [Value Based Question]
Answer:
(a) Minimum wastage of water is called water management.
(b) We should save water to prevent water crisis.
(c) Shishir is sincere, responsible and has capability of applying knowledge practically.

Question 4.
What is groundwater? What are the sources of water which are fed by groundwater?
Answer:
The wells, tubewells and handpumps are main sources of water for many people. The water in these sources is the groundwater. It is upper level of underground water which occupies all the spaces in the soil and rocks and form a water table as shown in the figure below:
Water A Precious Resource Class 7 Extra Questions Science Chapter 16 3
The upper limit of groundwater is called water table. It represents the depth of water filled area at a given place. The water table rises and falls depending upon the amount of rainwater that seeps into the groundwater and how much groundwater is drawn out for irrigation and industry. The seeping down of rainwater into the groundwater is called infiltration. The groundwater, thus gets recharged by this process.

At some places, the groundwater is stored between layers of hard rock below the water table. This is aquifer which contains the groundwater usable by tubewells and handpumps. These sources however, have limited sources of water and may get exhausted if used excessively.

Question 5.
Water is very precious for all the living beings.
What will happen in future, if we do not save water now? [NCERT Exemplar]
Answer:
Water is needed for various life activities. If we continue the misuse of water and do not conserve it, the groundwater level will be depleted. This may result into various consequences like

  • Lowering of the water table Excessive pumping can lower the groundwater table.
  • Reduced surface water supply Groundwater and surface water are connected. When groundwater is overused, the lakes, streams and rivers connected to groundwater, can also have little supply.
  • Loss of plants from land We fully depend on the plants for food directly or indirectly. Plants need water to prepare their food. If there will be scarcity of water on earth, the plants will be unable to prepare their food. This inturn will lead to the end of the life because world without plants means no food, no oxygen, not enough rain and other innumerable problems.
    Therefore, it is true that water is a precious resource.

Question 6.
All the rain that falls over an area is not utilised. Do you agree? Explain.
Answer:
Precipitation (rain) is a natural process and is a part of natural water cycle. It replenishes all the natural resources of water like ponds, lakes, river and finally oceans and seas too.
When we say utilisation of rainwater, we mean that rain in a particular area.
Yes, it is not properly utilised as most of the water is run off as surface water to the rivers and goes to oceans.
We can harness/harvest this water to local waterbodies like ponds, lakes and groundwater by proper planning as it is being done in some districts of Rajasthan successfully.

Light Class 7 Science Extra Questions Short Answer Type Questions

Question 1.
The distance between an object and a convex lens is changing. It is noticed that the size of the image formed on a screen is decreasing. Is the object moving in a direction towards the lens or away from it? (NCERT Examplar; HOTS]
Answer:
In case of convex lens, when we move the object far away from the lens, the size of image decreases and ultimately, when object is at infinity, it will form a point image at focus.

Question 2.
Two different types of lenses are placed on a sheet of newspaper. How will you identify them without touching? [HOTS]
Answer:
On identifying the letters of newspaper, we can differentiate the two types of lenses.
If image is large or magnified, then the lens is a convex lens and if the image is smaller or diminished in size for all the positions of object, then the lens is concave .

Question 3.
Briefly state the characteristics of image formed by a plane mirror.
Answer:
Characteristics of the Images Formed by a Plane Mirror
Now, we will describe the various characteristics of the images formed in a plane mirror by taking the example of the image of the candle.

  • When we see the mirror, the image of candle appears to be formed behind the mirror.
  • Now, pW a vertical screen behind the plane mirror (where the image of candle appears to be situated), then we will notice that the image of candle cannot be formed on the screen. Even if the screen is placed in front of the plane mirror, then the image of candle cannot be formed on the screen. Since, the image of candle formed in the plane mirror cannot be formed on a screen, which means that the image of candle in the plane mirror is a virtual image.
  • If we see the figure, then we will find that the length and breadth of the image of the candle and its flame to be the same as that of the original candle and its flame. The image of candle in the plane mirror is of the same size as the original candle.
  • Also if we see the figure, then we will find that the candle has a flame at the top and the image of candle also has a flame at the top. So, the top of candle remains at the top in the image. In the same way, the bottom of candle remains at the bottom in an image. Such an image is called an erect image (or upright image). Therefore, the image formed by a plane mirror is erect.

Question 4.
The side mirror of a scooter got broken. The mechanic replaced it with a plane mirror. Mention any inconvenience that the driver of the scooter will face while using it. [NCERT Examplar; HOTS]
Answer:
As we know that the side mirror of a scooter must be of convex mirror so that we can view a wide range of traffic spread over a large area. But if plane mirror is used, we are not able to see large area of traffic which may be difficult for driving vehicle and can cause accident.

Question 5.
We need a shiny surface for reflection. Explain why.
Answer:
Since, the extent of reflection depends upon the shine and smoothness of the surface. So, greater the shining and smoothness of the surface, greater will be the reflection. So, this is a reason why we require a shiny surface for reflection.

Question 6.
Differentiate between a plane mirror, concave mirror and a convex mirror without touching them.
Answer:
These mirrors can be differentiated by bringing our face close to each mirror turn by turn. Since, a plane mirror will produce an image of the same size as our face while a concave mirror will produce a magnified image and our face will look much bigger and on other sides, a convex mirror will produce a diminished image and our face will look much smaller like a small child.

Question 7.
The concave reflecting surface of a torch got rusted. What effect would this have on the beam of light from the torch? [NCERT Exemplar]
Answer:
If the reflecting surface of a torch got rusted, it produces diffused light with lower intensity and the objects are not clearly visible in this diffused and lower intensity of light.

Question 8.
Mention the type of image
(a) which can be formed on the screen.
(b) which cannot be formed on the screen.
Answer:
(a) The image which can be formed on the screen is real image.
(b) The image which cannot be formed on the screen is virtual image.

Question 9.
Mention any two letters of English alphabet whose image formed in a plane mirror appears exactly similar to the letters.
Answer:
Since, image formed by the plane mirror shows lateral inversion, i.e. left seems to right or vice-versa. But in the case of alphabets A and H, these letters show the same image in the plane mirror.

Question 10.
A shopkeeper wanted to fix a mirror which will give a maximum view of his shop. What type of mirror should he use? Give reason.
[NCERT Exemplar; HOTS]
Answer:
If a shopkeeper wanted to fix a mirror which will give him maximum view of his shop, he should use convex mirror.
In case of convex mirror, it will give a wider field of view, i.e. it can collect light from a large area spread over them.

Question 11.
State the correct sequence (1-7) of colours in the spectrum formed by the prisms A and B shown in the figure.
Light Class 7 Extra Questions Science Chapter 15 2
Answer:
When a white light is passed through a prism, it disperses into its seven constituent colours.
Light Class 7 Extra Questions Science Chapter 15 3

Question 12.
Suppose we wish to obtain the real image of a distant tree. Explain two possible ways in which we can do it. [NCERT Exemplar]
Answer:

  • In first case, we will use a concave mirror, as we know that concave mirror can form real image, i.e. image on screen. The image of distant tree will be at focus in case of concave mirror.
  • In second case, we can use a convex lens as it forms real image of a distant object at focus, i. e. image of distant tree in case of convex lens will be formed at focus.

Question 13.
Explain the term lateral inversion.
Answer:
When an image is formed by the mirror in such a way that the left side of image is object’s right side and right side of image is object’s left side. So, this process of change in the sides of the object as well as of image is known as lateral inversion.

Question 14.
State the characteristics of images formed by a concave mirror.
Answer:
The characteristics of image formed by a concave mirror are:

  • The image formed by a concave mirror is not always the same size as the object. It can be either larger or smaller depending on the distance of the object to the mirror.
  • The image formed by a concave mirror is inverted when the object is kept far from the mirror. So, when it is brought very close to the concave mirror, then an erect and enlarged image is formed.

Question 15.
Boojho made light from a laser torch to fall on a prism. Will he be able to observe a band of seven colours? Explain with a reason. [NCERT Exemplar; HOTS]
Answer:
No, he will not observe band of seven colours because laser light consists of monochromatic light of single colour.
But seven colours of bands are only observed, when a white light is passed through a prism and dispersion takes place.

Question 16.
Briefly explain why in ambulance words are written laterally inverted. [HOTS]
Answer:
In case of mirror, the image formed by it is laterally inverted, i.e. left seems to be right and right seems to be left. So, in ambulance there is emergency for patients to reach hospital and by viewing in rear mirror, it can be easily identified of a vehicle and everyone give him a way.

Question 17.
Assume, a person is standing in front of a plane mirror. The distance between the mirror and his image is 6 m. If the person moves 2 m towards the plane mirror, what would be the distance between the person and his image? [HOTS]
Answer:
Since, the image is 6m away from the plane mirror. So, it means that the object is also 6m away from the mirror.
Light Class 7 Extra Questions Science Chapter 15 4
[Because OP = PI]
So, when the person moves 2 m towards the plane mirror, then the distance between the person and the plane mirror will be equal to (6 m – 2 m) = 4 m, this means that distance between the image and the mirror will be 4m.
Light Class 7 Extra Questions Science Chapter 15 5
The distance between the person and his image = PO’+ PI’= 4 + 4 = 8m

Question 1.
Explain with the help of an activity that when seven colours are mixed together, then white colour is formed.
Answer:
Firstly, take a circular cardboard disc of about 10 cm diameter, then divide this disc into seven equal segments and paint the seven colours of white light (red, orange, yellow, green, blue, indigo and violet) on these segments (as shown in figure given ). Instead of painting the segments, we can also paste seven coloured papers on these segments. So, this disc painted with the seven colours of spectrum is called Newton’s disc. Now, make a small hole at the centre of the disc.
Light Class 7 Extra Questions Science Chapter 15 6
Fix the disc loosely on the tip of a refill of a ball pen. Be confirm that the disc can rotate freely. Now, rotate the disc quickly in day light. So, when the disc is rotated very fast, then all the seven colours mix together due to which the disc appears to be white (see figure). Therefore, the rapid rotation of Newton’s colour disc tells us that mixing of seven colours of the spectrum can give us white light.

Question 2.
It was observed that when the distance between an object and a lens decreases, the size of the image increases. What is the nature of this lens? If you keep on decreasing the distance between the object and the lens, will you still able to obtain the image on the screen? Explain. [NCERT Exemplar; HOTS]
Answer:
On decreasing the distance between the object and lens, the size of the image increases, the nature of the lens will be convex type.
If the distance between object and lens is less than the focus of the lens, then it forms a virtual image and this image cannot be obtained on a screen but formed on the same side of the object.

Question 3.
Give the definition dispersion of light. Also, explain why does it take place? Draw a diagram to show the dispersion of white light by a glass prism.
Answer:
In the year 1665, Newton discovered by his experiments with glass prisms that white light (like sunlight) consists of a mixture of lights of seven colours. Newton found that if a beam of white light is passed through a glass prism, then the white light splits to form a band of seven colours on a white screen . The band of seven colours formed on a white screen, when a beam of white light is passed through a glass prism, is known as spectrum of white light. The seven colours of the spectrum are Red, Orange, Yellow, Green, Blue, Indigo and Violet .
Light Class 7 Extra Questions Science Chapter 15 7
So, dispersion of light is phenomenon of splitting up of white light into seven colours on passing through a transparent medium like a glass prism. The formation of spectrum of seven colours indicates that white light is a mixture of seven colours. White light can be sunlight. So, now we can say that the sunlight consists of seven colours.
We can mix these colours to get white light. This can be done by using Newton’s disc, let us try this.

Question 4.
You are given three mirrors of different types.
How will you identify each one of them? [NCERT Exemplar]
Answer:
We can identify the mirrors by forming image of an object.

  • Plane mirror In case of plane mirror, image will be virtual, erect and of same size as that of object.
  • Concave mirror In case of concave mirror, image may be real, virtual and magnified or diminished.
  • Convex mirror In case of convex mirror, image formed will always be virtual, erect and diminished.

Question 5.
Namit was driving a car and suddenly became aware of a loud sound coming from behind. He looked through his rear view mirror and saw an ambulance. He recalled reading that such emergency vehicles often have their name written in the mirror (AMBULANCE) or writing, i. e. Light Class 7 Extra Questions Science Chapter 15 8
He quickly made way for the ambulance, murmuring a quick prayer for the speedy recovery of the patient inside the ambulance.
(a) Name the type of mirror which is used as a rear view mirror and why?
(b) Mention values did Namit exhibit. (Value Based Question]
Answer:
(a) Convex mirror is a mirror which is used as a rearview mirror. It is used to get a wide view of traffic behind.
(b) The values exhibit by Namit here is courtesy concerned for other, sympathy, knowledgeable.

Question 6.
One day, Ramesh’s friend was performing their respective experiments given by their teacher. While sitting in the practical lab instead of performing experiment, Ramesh was playing with his meter scale. All the sudden, he held the scale in his hand and started moving in front of tubelight, then he observed the seven colours of white light. After sometimes, he got scolded by his lab teacher for not performing the experiment.
(a) Give the name of phenomenon that leads to the formation of band of seven colours.
(b) Name the constituent colours of white light.
(c) Mention the values shown by Ramesh here. (Value Based Question]
Answer:
(a) Dispersion of white light is the name of phenomenon which leads to the formation of band of seven colours.
(b) There are seven constituent colours of white light, they are Violet, Indigo, Blue, Green, Yellow, Orange, Red (i.e. VIBGYOR).
(c) Ramesh seems to be quite innovative with respect to the scientific methods and also very eager to learn science regarding phenomena.

Question 7.
Last Sunday Girish’s mother, Priyanka was preparing the dinner in her kitchen for Girish and his father. Both of them were feeling so much hungry and they sat ideally on their respective chairs and having empty plates and spoons on their dinning table. They were shouting like a 5 years old child that they wanted the dinner so much eagerly in order to fulfil their stomach. At the sometime, Girish’s mother served the cooked food to both of them and the moment, when Girish was just about to eat the rice with the help of spoon, he noticed that the spoon has such a shining surface that it reflected the light rays incident on it.
(a) Explain the importance of shining surface in the reflection of light.
(b) Name the type of spherical mirror represented by the shining steel spoon.
(c) Mention the values shown by Priyanka here towards her family. [Value Based Question]
Answer:
(a) As we know that the extent of reflection depends upon the shining of surface. So, greater the shining of the surface, more will be the reflection.
(b) Both convex and concave mirrors are represented by the shining steel spoon.
(c) The values shown by Priyanka here is concern and a satisfaction that she gets after serving the cooked food to her son and her husband.
