Weathering of rocks leads to formation of sand, silt, and clay. On the basis of their mechanisms, following are the three types of weathering: 1. Physical Weathering 2. Chemical Weathering 3. Biological Weathering. Type # 1. Physical Weathering: Physical weathering of rocks is the breakdown of rocks into smaller size particles by pure mechanical processes without changing the chemical composition [...]
After reading this article you will learn about:- 1. Meaning of Soil Formation 2. Factors of Soil Formation 3. Stages 4. Processes. Meaning of Soil Formation: Soil formation is a process of two distinct phases: (i) Weathering of rocks and minerals i.e. disintegration (physical) and decomposition (chemical) of rocks and minerals; (ii) The development or the formation of true soil [...]
After reading this article you will learn about the factors and process of soil formation. Factors of Soil Formation: Soil development or soil genesis, is the result of a number of factors known collectively as soil formers, some of which are active and some passive in nature. These are: 1. Parent material, 2. Relief (topography), 3. Climate, 4. Biosphere (vegetation, [...]
