Now, let us look into key differences between clayey and sandy soil. Clayey soil is the densest and heaviest type of soil while sandy soil consists of small particles of weathered rock.
Additional information: The process of formation of soil can happen either one of the three ways,
1) Biological weathering - In this, the living organism breaks down and weakens the rock and then chemical or mechanical weathering is initiated.
2) Mechanical weathering - It is observed near the earth’s surface and is influenced by physical forces like temperature, wind, etc.
3) Chemical weathering - The rock breaks down due to chemical reactions.
Note: The function of soil is as follows,
- It provides habitat for organisms like earthworms, etc.
- It is a medium through which a plant grows.
- It is a very important component of the biosphere.
