Answer Details
The main process of soil formation in humid tropics is laterization. Laterization occurs when soil is subjected to high temperatures and heavy rainfall over a long period of time. This process results in the leaching of important nutrients from the soil, leaving behind a soil that is rich in iron and aluminum oxides. These oxides give the soil its characteristic red or yellow color. The soil becomes hardened and compacted, and its ability to retain water is greatly reduced. This makes it difficult for plants to grow, and often leads to the formation of dense tropical rainforest ecosystems.
