Question

which process is defined as breaking down rocks into smaller pieces without changing the rocks compositions?
○ erosion
○ oxidation
○ chemical weathering
○ mechanical weathering

Explanation:

• Erosion is the process of transporting weathered materials, not just breaking rocks.
• Oxidation is a chemical reaction (part of chemical weathering) that changes the rock's composition.
• Chemical weathering changes the rock's chemical composition.
• Mechanical weathering breaks rocks into smaller pieces without changing their composition.

Answer:

mechanical weathering
