Soil is made up of crumbled rocks. Three natural forces-wind, flowing water and emperature-weaken the rocks and break them into pieces that are like small stones.These pieces are called the parent material because soil is formed from this material. In India, a wide range of soils is found. On the basis of the natural environmental processes that produce them, these can be broadly divided into two groups, in situ soils and transported soils (formed by the transport of eroded material. The in situ soils get their distinguishing features from the parent rock.
