Question
Explain the process of the formation of Block mountains.
✓
Answer
- Because of internal movements, horizontal waves moving away from each other are formed.
- This causes tension on the layers of rocks leading to the formation of fractures in the rocks called as faults.
- Similarly, waves coming towards each other in hard rocks also form faults due to compression.
When a part of the earth’s crust in between two parallel faults is lifted, it looks like a block. Such a landform is called as a Block mountain.
