Final answer:
Mechanical weathering involves physical breakdown of rocks, while chemical weathering involves chemical alteration of rock materials.
Step-by-step explanation:
The difference between mechanical weathering and chemical weathering lies in the processes and mechanisms involved. Mechanical weathering is the physical breakdown of rocks into smaller fragments without any change in their chemical composition, whereas chemical weathering involves the alteration of rock materials through chemical reactions. Examples of mechanical weathering include frost wedging and exfoliation, whereas examples of chemical weathering include dissolution and oxidation.
