WebSep 18, 2024 · Physical weathering, also called mechanical weathering, is a process that causes the disintegration of rocks, mineral, and soils without chemical change. The primary process in physical weathering is abrasion (the process by which clasts and other particles are reduced in size). What are the 7 types of chemical weathering? WebApr 12, 2024 · Weathering of rocks can be chemical as well as mechanical. Generally, mechanical weathering is defined as breaking of rock into smaller pieces by fracturing and abrasion by weathering agents such as water, glacier, wind; this phenomenon gives rise to chemical weathering as it causes the disintegration of smaller rock pieces, which in turn ...

Abrasion is another type of mechanical weathering. With abrasion, one rock bumps against another rock. Gravity causes abrasion as a rock tumbles down a slope. Moving water causes abrasion; it moves rocks so that they bump against one another ( Figure below). Strong winds cause abrasion by blasting sand against rock surfaces.
