Which of the following climates is most suited for physical weathering?

A. Dry

B. Hot

C. Cool

D. Warm

A

Answer: C. Cool

In physical weathering, rocks are weathered or broken apart without any form of chemical intervention. In other words, their chemical composition is not changed. It is also referred to as mechanical weathering. Physical weathering occurs frequently in cold climate regions.

This is so because the repeated freezing and melting of water in the small cracks and crevices in the surface of the rock will lead to the repeated expansion and contraction of the rock. Expansion of the small cracks causes pressure on the surrounding rock by making the cracks wider. This in turn causes the weakening of the rock and then weathering.
