How do physical and chemical weathering occur

WebPhysical weathering, also called mechanical weathering, is a process that causes the disintegration of rocks, mineral, and soils without chemical change. The primary process … WebChemical weathering is caused by rain water reacting with the mineral grains in rocks to form new minerals (clays) and soluble salts. These reactions occur particularly when the water is slightly acidic. Where does it occur? These chemical processes need water, and occur more rapidly at higher temperature, so warm, damp climates are best.
