- When large areas are broken and displaced vertically, block mountains are created.
- The uplifted blocks are termed as horsts.
- Lowered blocks are named as graben.
- Rhine valley and Vosges are good examples of such block mountains.
Some more examples of this type of mountains/landforms:
- Rift valley of Narmada and Tapi
- Deccan Plateau
- Meghalaya Plateau
- Drakeusburge (in South Africa)
