Question

Mechanical and chemical weathering depend on _______________________________________ and temperature.

A.) acid
B.)air
C.)water

Answer 1

C.)water

Step-by-step explanation:

Weathering is the physical disintegration and chemical decomposition of rocks to form sediments and soils.

Mechanical weathering is the breaking down of rocks by physical means.

Chemical weathering is the decay of rocks by chemical means.

• Both chemical and mechanical requires water for the processes to occur.
• Water is usually the medium for chemical actions to take place in a rock.
• For mechanical processes, water in different phases plays a very important role too.
