The type of erosion that consists of a thin, uniform layer of soil being eroded from a field is the sheet erosion. Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water. Sheet erosion is the uniform removal of soil in thin layers by the forces of raindrops and overland flow. This type of erosion is responsible for extensive soil loss in both cultivated and non-cultivated environments.
