Question 9.
Explain any three main characteristics of the mineral resources of India.
Answer:
The major characteristics of mineral resources are as follows:

1. Their distribution over the earth surface is uneven i.e. some regions may have rich in minerals whereas others may be lack behind in availability of minerals,
2. Minerals of good quality are less in amount and minerals of low quality are more in the amount on earth i.e. quality and quantity of minerals have an inverse relationship.
3. Minerals are exhaustible, i.e. once used they can’t be used again. Minerals take a long time to develop geologically and once they exhausted they cannot be available at that time for use.

Question 10.
