How is soil formed?
Soil Formation: How the soil formed? well, soil formation is a very long process and actually begins with the weathering of rocks into small fragments. The origin of soil is from rocks (parent material), usually formed when rocks are exposed to the atmosphere in the process of physical and chemical decomposition. Parent material (usually rocks) and the process of soil formation decide the soil properties. The soils in India are divided into 2 broad categories based on their formation.
