WebSoil formation takes place by the process of weathering when the rocks break down to form soil particles. This rock degradation takes millions of years to complete. Physical, chemical, and biological weathering are the responsible factors for the creation of soil. The influences of heat, cold, water, wind, and rain cause the bedrock to crumble. WebA theory of soil genesis should be consistent with the exist-ence of soils of the world as a continuum, of features common to all soils, of the normal gradations from one soil to its neighbors, and of differences expressed to various degrees among soils.
