Importance (Functions) of soils
Soils provide plants with essential minerals and nutrients. Soils provide air for gaseous exchange between roots and atmosphere. Soils protect plants from erosion and other destructive physical, biological and chemical activity. Soils hold water (moisture) and maintain adequate aeration.
Some of the factors responsible for the formation of soil is climate, temperature, vegetation and so on. Climate is responsible because it affects the time of weathering of rocks. Temperature plays a significant role because it causes shrinking, swelling, and frost action, which allows small stones to breaks.
