Question

How is block disintegration different from granular weathering?

Answer 1

Block disintegration is the breaking of rocks into large blocks due to stress caused by temperature fluctuations causing expansion and contraction. Granular weathering, on the other hand, involves rocks breaking into smaller fragments because different minerals expand and contract at different rates under temperature changes. Thus, block disintegration breaks rock into large blocks, while granular weathering produces small grains or fragments.
