Question

Which of the following process contributes to soil formation?

• A. Physical process
• B. Chemical process
• C. Biological process
• D. All of the above

Answer 1

The correct option is D

All of the above

Soil formation is influenced by physical, chemical and biological processes. Physical factors like water and wind aid the transfer of soil from one region to another. Chemical processes loosen the forces in between the molecules present in rocks until they finally become soil. Biological factors like living organisms living in the soil convert the dead and decaying elements in the soil to manure which becomes an element of the soil.
