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. WebSoil processes and profiles are discussed in relation to the landscape, the geosphere, and the biosphere. Emphasis lies on the universality of soil-forming processes in past and present, and on the soil as a dynamic entity that forms part of the total environment. Complexity of genetic processes in time and space is given much attention.
