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 shallo wer and decreases crop yield. * test! erosion : It involves the removal of soil by rainwater effluence through small finger-like channel. * Channel or gully erosion: occurs when the hoi polloi of surd run off increases and attains more velocity. The rills enlarge into gullies. At an gain ground stage, gullies result in ravines making the soil disincline for cultivation. deform Erosion The other cause for erosion is wind.
