What is Soil? How is it formed? |
|
Answer» The loose and unconsolidated material which forms the upper layer of the crust is called soil. It is found in layers or horizons. Its thickness varies from some cm to meters. It consists of many mineral and organic particles, humus, bacteria, etc. Soil formation is a slow process. Soil is formed through the chemical and mechanical weathering of rock cover. Parent materials derived from rock cover and humus together lead to soil formation. Soil is the end product of the physical, chemical, biological and cultural factors which act and react together. |
