Q: What is the term for the slow wearing down of rocks on earth's surface? Read this paragraph and choose the correct option from the provided answers: Weather makes life interesting. Weather also causes weathering. Weathering is the slow wearing down of rocks on Earth's surface. Wind-blown sand scours rocks like sandpaper. Glaciers of ice scrape across rock surfaces like a file.
