Erosion
The energy for erosion comes from five sources: gravity, the sun, Earth’s rotation, chemical reactions, and organic activity. These forces work together to break down and carry away the surface materials of Earth.
The first step in erosion is weathering. Weathering of solid rock, produces loose sediment, and makes the sediment available for transport. Weathering consists of a number of related processes that are of two basic types: mechanical or chemical. Please click on the weathering tab to learn more about weathering.
There are three types of erosions. They are water, wind, and glaciers. Go to the links to learn about wind and water.
