Answer 1

Answer:

Weathering processes are divided into physical and chemical weathering. Physical weathering involves the breakdown of rocks and soils through the mechanical effects of heat, water, ice, or other agents. Chemical weathering involves the chemical reaction of water, atmospheric gases, and biologically produced chemicals with rocks and soils. Water is the principal agent behind both physical and chemical weathering,[1] though atmospheric oxygen and carbon dioxide and the activities of biological organisms are also important.[2] Chemical weathering by biological action is also known as biological weathering.[3]
