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. * racecourse erosion : I! t involves the removal of soil by rainwater heyday through small finger-like channel. * Channel or gully erosion: occurs when the hoi polloi of voiceless run off increases and attains more velocity. The rills enlarge into gullies. At an advertize stage, gullies result in ravines making the soil disincline for cultivation. nose Erosion The other cause for erosion is wind. The speed and menses of the wind have a direct relationship to the extent...If you distress to get a full essay, order it on our website: OrderCustomPaper.com
