Weathering explains the breaking down or dissolving of rock and minerals on the surface of the earth. Water, ice, acids, salts, plants, animals, and temperature changes are all presentations of weathering. Weathering and erosion frequently change the rocky landscape of the earth. Weathering is frequently the first step in the production of soils. If you want to know more about weathering, try this quiz.
