Give a brief note on soil formation
Answers
Explanation:
Soil is the thin layer of material covering the earth’s surface and is formed from the weathering of rocks. It is made up mainly of mineral particles, organic materials, air, water and living organisms—all of which interact slowly yet constantly.
Most plants get their nutrients from the soil and they are the main source of food for humans, animals and birds. Therefore, most living things on land depend on soil for their existence.
Soil is a valuable resource that needs to be carefully managed as it is easily damaged, washed or blown away. If we understand soil and manage it properly, we will avoid destroying one of the essential building blocks of our environment and our food security.
Soils are formed by physical or chemical disintegration of rocks. Thus, the chief parent material of soil is the rock. ... The processes responsible for soil formation are a part of geological cycle involving weathering, denudation, erosion, transportation, deposition, and upheaval.
