Weathering is more rapid in humid, tropical regions than in temperate regions. This is because tropical areas receive more rainfall, which encourages chemical weathering such as carbonation. Also, tropical areas are warmer, and the rate of chemical weathering doubles with every rise of 10°C. Chemical weathering occurs in locations with high temperatures and plenty of water, such as humid tropical regions. All these weathering processes have a certain importance, but chemical weathering plays the most relevant role in the disintegration of minerals and rocks in humid tropical zones. The Equatorial regions experience chemic weathering because (a) the equator regions have high temperature and receive rainfall throughout the year, (b) the leaves the forests in this region fall on the ground and form humic acid, which facilitates chemical decomposition of the rocks.

In dry and cold regions, physical weathering is the dominant type of weathering. Landforms tend to be sharp and angular and soils tend to be thin. Physical weathering happens especially in places where there is little soil and few plants grow, such as in mountain regions and hot deserts. Weathering is more rapid in humid, tropical regions than in temperate regions. This is because tropical areas receive more rainfall, which encourages chemical weathering such as carbonation. Also, tropical areas are warmer, and the rate of chemical weathering doubles with every rise of 10°C. Chemical weathering is a long and slow process, which is predominantly high in hot and humid regions such as the regions in the equatorial, tropical, and subtropical zones of the Earth. Chemical weathering is the dominate weathering process in warm, humid environments. It happens when water, oxygen, and other reactants chemically degrade the mineral components of bedrock and turn them into water-soluble ions which can then be transported by water. A tropical rain forest climate is usually found at latitudes within 15 degrees North and South of the equator, which are dominated by the Intertropical Convergence Zone (ITCZ). The climate is most commonly found in South America, Central Africa, Southeast Asia and Oceania. The chief agents of chemical weathering are air and water. By the action of this two agents, the minerals in rock undergo chemical change and form a new chemical substance. Chemical weathering is more dominant in the area of humid climate. The more water present, the faster weathering occurs. Temperature is also important. Warmer temperatures promote faster reactions, so chemical weathering is more effective in warm climates. Thus, warm, humid climates tend to have the most rapid weathering. These chemical processes need water, and occur more rapidly at higher temperature, so warm, damp climates are best. Chemical weathering is the first stage in the production of soils.
