Question

Name the processes involved in exfoliation.

Answer 1

1. Heating: During the day, rocks are heated by the sun, causing them to expand.

2. Cooling: At night, the rocks cool down and contract.

3. Repeated Expansion and Contraction: The continuous cycle of heating and cooling causes the outer layers of the rock to crack.

4. Peeling Off: Over time, these cracks cause the outer layers to peel off in thin sheets or layers.

This process leads to the gradual breakdown of rocks, particularly in areas with large temperature differences between day and night.
