Soil
The thin layer of grainy substance covering the surface of the earth and closely linked to the land. Landforms determine the type of soil. Soil is made up of organic matter, minerals and weathered rocks found on the earth through the process of weathering. The right mix of minerals and organic matter make the soil fertile.
Factors of Soil Formation:
Parent Rock: The parent rock determines the colour, texture, permeability, chemical property and mineral content of the soil.
Climate: Temperature and rainfall influence the rate of weathering.
Relief: Altitude and slope determine the accumulation of soil at a place.
Flora, fauna and microorganism: These are the biotic factors which affect the rate of humus formation.
Time: Time determines the thickness of soil profile.
