Question

Give a geographical reason for the following:

Physical weathering is also called mechanical weathering.

Answer 1

Physical weathering is also called mechanical weathering because it involves the breaking down of rocks into smaller pieces through physical forces without changing their chemical composition. The process occurs due to forces like temperature fluctuations, freeze-thaw cycles, pressure release, and the action of plant roots. Since these processes physically break the rock into smaller fragments, it is referred to as mechanical weathering.
