Which of the following is not a process of chemical weathering?
Answer Details
The correct answer is attrition. Attrition is a physical weathering process that occurs when rocks are broken down into smaller pieces through abrasion, collision, or friction. On the other hand, the other options listed are all processes of chemical weathering, which involves the breakdown of rocks through chemical reactions with water, air, or other substances. For example, oxidation is the reaction of oxygen with minerals in rocks to form oxides or rust, hydration involves the reaction of water with minerals to form new compounds, and carbonation is the reaction of carbon dioxide with water to form carbonic acid, which can dissolve certain types of rocks.
