The qualities of soil get determined by the conditions in which it weathers. Some of the essential procedures are as follows:
Physical Weathering: Changes in temperature or pressure, or both, are induced by physical forces such as the sun, wind, and ice, which increase or reduce the volume of rocks, causing them to disintegrate.
Chemical Weathering occurs when various chemical components, such as rainfall, react with the minerals in the rocks to generate new minerals or salts.
Biological Weathering: Living creatures such as plants, animals, and other microbes carry out this process by secreting or releasing acids that destroy the rocks.
