Briefly define the following using your own words. 1. Mechanical Weathering 2. Frost Wedging 3. Exfoliation 4. Chemical Weathering 5. Dissolution
Answer (1)
Answer:Mechanical Weathering: The process where rocks break down into smaller pieces without changing their chemical composition, often due to physical forces like wind, water, or temperature changes.Frost Wedging: A type of mechanical weathering where water gets into cracks in rocks, freezes, and expands, causing the rock to crack and break apart.Exfoliation: A weathering process where outer layers of rock peel off in thin sheets or slabs, usually due to temperature changes or pressure release.Chemical Weathering: The process where rocks are broken down through chemical reactions, which alter their mineral composition and structure, often involving water and gases.Dissolution: A type of chemical weathering where minerals in rocks dissolve in water, leading to the gradual breakdown of the rock.
