Soil is formed by the process of ‘weathering’ of rocks, that is, disintegration and decomposition of rocks and mineral at or near the earth’s surface through the actions of natural or mechanical and chemical agents into smaller grains.
Factors affecting formation of soil may be atmospheric, such as changes in temperatures and pressure; erosion and transportation by wind, water and glaciers; chemical action such as crystal growth, oxidation, hydration, carbonation and leaching by water, especially rainwater, with time.
Soil formation differs according to the effect of various environmental factors which include parent material;climatic conditions,the most important aspect of which is weathering of rocks and erosion;and finally the surface relief and drainage .Process of soil formation is called Pedogenesis.
