Explain the process of soil formation.

संक्षेप में उत्तर

Soil and its Formation:

Soil is a mixture of organic matter, minerals, gases, liquids and organisms that together support life.
Soils are produced from rocks through the processes of weathering and natural erosion.
Water, wind, temperature changes, gravity, chemical interaction, living organisms, and pressure break down parent material.
It leads to the formation of loose material.
In the course of time, they further break down into fine particles and releases the locked minerals in the rock.
