\nThe correct answer is D) Exfoliation.
\n<\/section>\n
\nExfoliation is a type of physical weathering process, not chemical weathering. Chemical weathering involves the decomposition of rocks through chemical reactions, such as solution, carbonation, and oxidation.
\n<\/section>\n
\nChemical weathering processes include Solution (minerals dissolving in water), Carbonation (reaction with carbonic acid, often formed from CO2 in water), Oxidation (reaction with oxygen, e.g., rusting), Hydration (addition of water to mineral structures), and Hydrolysis (reaction of water with minerals to form new compounds). Physical weathering processes, like exfoliation, involve the breakdown of rocks into smaller pieces without changing their chemical composition. Exfoliation is the process where outer layers of rock peel off due to pressure release or thermal expansion\/contraction.
