Question

Explain the role of the sun in the formation of soil.

Answer 1

The sun plays an important role as a natural factor in rock weathering for the creation of the soil.

1. During the day it heats rocks. Heating induces an expansion of the rocks.
2. The rocks cool down and contract throughout the night.
3. Different sections of a rock expand and contract at different speeds, resulting in smaller bits or fragments (boulders) being cackled and broken up.
