Question

Describe the process of soil formation
(100 word)​

Answer 1

Answer:

Formation of soil:

The soil is created by the process of weathering or disintegration of parent rocks by physical, chemical and biological agents. Soil formation is a slow process that takes thousands of years. Soil can be formed by three processes given below

Mechanical Weathering

This is usually observed near the surface of the earth. It is called physical weathering, as this method is influenced by physical forces such as wind, water and temperature.

Chemical Weathering

Chemical weathering occurs when rocks are broken down by chemical reactions. Such types of weathering can change the chemical composition of the soil.

Biological Weathering

The lichens growing on the rocks discharge certain chemicals that break down the rock into a fine powder and form a thin layer of soil. The mosses also develop on the rock surface and further break the rock. The roots of the trees get into the cracks of the rocks and push them to widen, thereby, breaking the rocks.

Answer 2

Explanation:

Soil Minerals form the basis of soil. They are produced from rocks ( parents material) through the processes of weathering and natural erosion. Water , Wind, Temperature change, gravity, chemical interaction , living organisms and pressure differences all help Break down parent material .Soil Is formed by the Combination of physical, chemical and biological processes in which huge Rock are broken down into smaller particles over a long period of Time . Gradually, these cracks cause the Rock's to Break down into smaller pieces. With Time, these smaller pieces convert into particles and form Soil. The soil is formed by weathering or disintegration of parents Rock's by chemical process.
