What is meant by arid soils and soil erosion explain in detail
Answers
Explanation:
Soil erosion is a particularly serious problem worldwide (Boardman, 2006; Manzatto et al., 2002; Orimoogunje, 2014). It is estimated that erosion of agricultural soils in the United States is responsible for loss of an average of 30 tons per hectare per year, about eight times greater than the rate of soil formation in the human lifetime. Soil erosion is accelerated by a marked landscape slope, removal of vegetation to create agricultural land, drought, soil tillage, wind, or water, but erosion by water is the most widespread and serious. This is because the force of gravity on water and ice may lower the shear strength of landscape slopes, making soils behave like plastics or, under very moist conditions, like fluids (Abrahams, 1986; Brunsden, 1988; Clague and Robert, 2012; Goudie and Viles, 1997; Kanungo and Sharma, 2014; Selby, 1993).
Explanation:
Arid environments are extremely diverse in terms of their land forms, soils, fauna, flora, water balances, and human activities. Because of this diversity, no practical definition of arid environments can be derived. However, the one binding element to all arid regions is aridity
Soil erosion is the wearing away of the earth’s surface by the force of wind and water, and consists of soil particle dislodgement, entrainment, transport, and deposition.
