Layers Of Soil

The soil is the topmost layer of the earth’s crust consisting of air, water, inorganic minerals (rock, sand, clay, and slit), and organic matter (dead plants and animals). It forms the source of food for plants. It provides shelter for many animals such as insects, centipedes, burrowing animals, microorganisms, and many others. It is thus also called the ‘skin of the earth.’ There are different soil types, each having unique characteristics like color, texture, structure, thickness, mineral content, and organic matter.
