Concept:Chemical weathering decomposes rocks through chemical changes in their minerals.
Explanation:Oxidation, hydration, and carbonation are all chemical weathering processes.
Oxidation is the reaction of minerals with oxygen.
Hydration involves the chemical absorption of water into minerals.
Carbonation is the reaction of minerals with carbonic acid.
Each of these processes alters the chemical composition of the rock.
Attrition is the grinding and wearing down of rock fragments by collision during transport.
Attrition is a physical or mechanical weathering process, not a chemical one.
Answer:Attrition is not a process of chemical weathering.
