💨 Weathering: Breaking Down Rock
Weathering is the process that breaks down rocks and minerals into smaller pieces through physical and chemical processes. This quiz explores the differences between mechanical and chemical weathering, the role of water and temperature, and how weathering connects to erosion and soil formation. **What you'll learn:** - Distinguish between mechanical weathering (freeze-thaw, abrasion, plant roots, exfoliation) and chemical weathering (oxidation, dissolution, hydrolysis) - Explain how water, temperature changes, and acids break down rocks - Connect weathering to erosion and the formation of soil
