C. In chemical weathering, the composition of the weathered substance is changed.

Explanation: Physical (mechanical) weathering breaks rock into smaller pieces without altering mineral composition. Chemical weathering alters the minerals through reactions (e.g., hydrolysis, oxidation, dissolution), changing the rock's chemical makeup. Options B and D are incorrect because neither type is always faster — rate depends on conditions.
