is weathering of rocks a physical and chemical change

Answer 1

it can be physical, chemical, and also biological

Answer 2

ANSWER:

Depending upon the parent Rock material the soil is also of different types. Weathering process can be a physical and as well as chemical change.

EXPLANATION:

• Weathering is defined as the process of breaking down of large sized stones into smaller particles due to the course of action of rain, wind and heat.
• This is a very slow process and it takes thousands of years to be happened. The physical breaking down of a large stone includes heat, pressure and gravitational phenomenon’s.
• The chemical breakdown of large stones include the chemical reaction between parent Rock material and rainwater and some other chemicals.
• Thus we can see that both the factor are responsible for weathering of rocks. Therefore the weathering process is chemical as well as physical change.
