Physical weathering: It is also called Mechanical weathering. It includes the breaking up of rocks without changing their composition. It means the disintegration of rocks by mechanical means. This type of weathering results from the action of temperature changes, frost, wind, and rainfall. It is important in dry areas.
Chemical weathering: The decomposition of rocks by chemical processes is called chemical weathering. This type of weathering produces a chemical change in minerals of rocks. It results from the action of weak acids and atmospheric gases like oxygen, carbon dioxide, hydrogen. It involves the process of oxidation, carbonation, solution and hydration. It is important in hot humid areas.
