Soil is formed due to the weathering of rocks by various factors such as air, water and wind. The formation of soil takes place over a million years. The river water cuts various rocks while flowing and brings them and deposits them on the banks. These tiny particles of rocks contribute to the formation of soil. Other various factors such as freezing and thawing and winds also contribute to the breakage of rocks, this helps in soil formation. The death of various animals and plants also contribute to the organic content of the soil and form the upper fertile layer of the soil called the humus.

Soil is the upper layer of the earth's surface where plants grow. Soil is important for life on Earth. It consists of tiny grains of rock, minerals, water and air. Soil is the source of mineral nutrient and water for plants. Roots of the plants absorb nutrients from the soil.
