Chemical weathering is prominent in hot and humid zones.

Weathering is the disintegration, breaking down and decomposition of components in the earth’s crust through the action of natural or other agents. Weathering can occur due to exposure to the earth’s atmosphere. Weathering is controlled and determined by various factors like temperature, rainfall, vegetation and movements of other components in the earth’s crust. Weathering can be physical, chemical or biological.

Chemical weathering is the decomposition of components in the earth’s crust through chemical reactions. It changes the chemical composition of rocks. Oxygen, carbon dioxide and hydrogen are the agents of decomposition. Oxidation, carbonation, solution and hydration are the different types. Chemical weathering is usually common in places with very hot and humid climates. It occurs in the climatic conditions of the hot and humid regions of the equators, tropics and sub-tropics. The action of the constant availability of water and the rising temperature is responsible for the faster weathering of rocks compared to other regions. The solution and hydration methods of chemical weathering will be most common in such climates. The reaction between the atmospheric humidity and other elements are responsible for the higher rate of weathering.
