Topography
- Topography like parent materials is another passive control factor.
- The influence of topography is felt through the amount of exposure of a surface covered by parent materials to sunlight and the amount of surface and sub-surface drainage over and through the parent materials.
- Soils will be thin on steep slopes and thick over flat upland areas. Over gentle slopes where erosion is slow and percolation of water is good, soil formation is very favorable.
- Soils over flat areas may develop a thick layer of clay with a good accumulation of organic matter giving the soil a dark color.
Soil Formation| Class 11 Geography Notes
Soil is a dynamic medium with constant chemical, physical, and biological activities. Soil is a result of decay, it is also the medium for growth. It is a changing and developing body. It has many characteristics that fluctuate with the seasons. Organic matter increases when leaves fall or grasses die. The process of soil formation is a continuous one, and it is constantly being affected by the factors that contribute to it. Soil is a valuable resource, and it is important to protect it from erosion and other forms of degradation.
