Weathering is a group of natural processes that break rock into smaller pieces over time. Erosion occurs when rock and soil are transported.tthMechanical & Chemical WeatheringThe two types of weathering are mechanical and chemical. Mechanical weathering is the physical decomposition of rocks. Chemical weathering is the decomposition of rocks by chemical reactions.windwaterwavesweatheringphysical decompositionchemical reactionsflowing icegravityHow Is Rock Eroded?Rock can be eroded by many forces such as and gravity. These forces all contribute to sculpting the Earth’s landscape.Photos courtesy of USFWS, NPS, NASA, & USGS.erosionMechanicalChemicalplant growthForces of weathering and erosion are constantly reshaping the Earth’s surface.
