Definition
Soil is a thin layer of material on the Earth's surface in which plants have their roots. It is made up of many things, such as weathered rock and decayed plant and animal matter. Soil is formed over a long period of time. Soil Formation takes place when many things interact, such as air, water, plant life, animal life, rocks, and chemicals.
