The soil is created by the process of weathering or disintegration of parent rocks by physical, chemical and biological agents. It is a slow process that takes thousands of years. The physical and chemical decomposition is principally done by water, wind, and climate. As a result of these processes, large rock pieces are converted into smaller pieces and eventually to the soil. Living organisms such as insects and microorganisms make the soil ready for the plants to grow. The growth of roots of plants further adds to the weathering of rocks and thus forms soil.
