Weathering and Erosion with Skittles Over time, rocks that are exposed at Earth’s surface undergo mechanical and chemical weathering. Mechanical processes break down rock into small particles called sediment. Chemical processes can be caused by weak acids that react with minerals in the rock to produce new substances.
