It is used a lot in the context of our Earth. The small pieces are deposited somewhere else through a process called deposition. These forces can be water, wind, and ice. Wind erosion is one of the weakest kinds of erosion. Cold weather causes water inside tiny cracks in rocks to freeze. The huge masses of ice called glaciers also cause erosion.

These forces also move bits of rock and earth to new places. Erosion can be very harmful to farmland. All these materials are called sediments. If that broken-down material gets moved at all by water, wind or ice, then erosion has occurred. Valley erosion is occurring due to the flow of the stream, and the boulders and stones (and much of the soil) that are lying on the stream's banks are glacial till that was left behind as ice age glaciers flowed over the terrain. One of the most famous examples of wind erosion occurred in the Dust Bowl, when wind erosion severely damaged farming communities. Large tropical rivers like the Paraná, Indus, Brahmaputra, Ganges, Zambezi, Mississippi and the Amazon carry huge amounts of sediment down to the sea.
