Question

Give a geographical reason for the following:

Biological weathering is also known as organic weathering.

Answer 1

Biological weathering is also known as organic weathering because it is caused by the activities of living organisms such as plants, animals, and microorganisms. These organisms, through their growth, movement, and metabolic processes, help in the breakdown of rocks. For example, plant roots penetrate rocks, animals burrow into the ground, and microorganisms release organic acids that chemically alter minerals. Since these processes are driven by organic life forms, biological weathering is often referred to as organic weathering.
