Chemical weathering is both rapid and intense in the humid tropics because of high rainfall and temperature. Chemical weathering is the breakdown of rocks through chemical processes such as dissolution, oxidation, and hydrolysis. In the humid tropics, the combination of high rainfall and temperature increases the rate of chemical weathering because water and heat are key components in many chemical reactions that break down rocks. The high rainfall increases the availability of water for chemical reactions, while the high temperature speeds up the reactions. As a result, chemical weathering in the humid tropics is more rapid and intense than in other regions with lower rainfall and temperature. The presence of easily weathered rocks and large volumes of run-off can also contribute to chemical weathering in the humid tropics, but they are not the main factors.
