Soil Erosion

SOIL EROSION Land is also a extraordinary castratenative , needed for agriculture and occupation. Land is under obligate repayable to increasing population. Land for agriculture has to be fat in order to be able to support a commodity crop. The fertility of overthrow lies in the quality of the crap. alter is a dynamic, non-renewable inborn resource, which supports life on earth, in which umteen chemical, forcible and biological activities go on constantly. get is organise as a result of weathering of rocks. Soil has many storys (soil horizons), the extremum al around layer is called the surface soil and is the most fertile. The removal of this topsoil is called soil wearing away. Soil eroding is a geologic process of soil adulteration wherein soil particles are degage and transported by the various agents of wearing away. These agents of wearing include water, wind, glaciers, and gravity. Soil corroding is a natural process, just now becomes a paradox when human activity causes it to occur much(prenominal) faster than under natural conditions. Types of soil erosion Water erosion Soil erosion by water is the result of rain detaching and transporting indefensible soil is known as water erosion * Splash erosion: caused by falling torrential rain. 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. * rails erosion : It involves the r! emoval of soil by rainwater sack through small finger-like channel. * Channel or gully erosion: occurs when the hoi polloi of strong run off increases and attains more velocity. The rills enlarge into gullies. At an erect stage, gullies result in ravines making the soil disincline for cultivation. plagiarize Erosion The other cause for erosion is wind. The speed and intent of the wind have a direct relationship to the extent...If you impoverishment to get a full essay, order it on our website: OrderCustomPaper.com
