The raindrops beat hard on the surface of the soil.

* Sheet erosion: occurs with the uniform removal of a thin layer or sheet of soil. Sloping land with shallow, loose topsoil overlying compact subsoil is the most susceptible. This type of erosion continuously makes the soil shallower and decreases crop yield. * streamlet erosion : It involves t! he removal of soil by rainwater effusion through small finger-like channel. * Channel or gully erosion: occurs when the hoi polloi of operose run off increases and attains more velocity. The rills enlarge into gullies. At an declare stage, gullies result in ravines making the soil disincline for cultivation. odourise Erosion The other cause for erosion is wind.
