WebWeathering is the process of disintegration and decomposition of rocks. It is due to the action of climate, plants, animals and other living organisms which cause the rocks to break down physically, chemically and biologically. There are three types of weathering. They are physical weathering, chemical weathering and biological weathering. WebPhysical 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). Physical weathering can occur due to temperature, pressure, frost ...
