Clastic sediments are composed of fragments of older rocks that have been transported from their place of origin. Rocks eroded through physical erosion often form clastic sediments. Physical erosion often causes rocks to get smaller or smoother. Physical erosion describes the process of rocks changing their physical properties without changing their basic chemical composition. This transported material is called sediment. The brown color indicates that bits of rock and soil are suspended in the fluid (air or water) and being transported from one place to another. ![]() If the wind is dusty, or water or glacial ice is muddy, erosion is taking place. Most erosion is performed by liquid water, wind, or ice (usually in the form of a glacier). ![]() Erosion is the opposite of deposition, the geological process in which earthen materials are deposited, or built up, on a landform. A similar process, weathering, breaks down or dissolves rock, but does not involve movement. Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water.
