Question

Quizplus · Accepted Answer

Mechanical weathering is the physical breakdown of rock into smaller pieces, without changing the rock's chemical composition. Erosion involves the transportation of the broken down rock by natural forces such as water, wind, or ice. Chemical weathering involves a chemical change in the rock's composition.
