Detailed Solution

The denudation of the soil cover and subsequent washing down is described as soil erosion. Erosion through wind, water, and the glacier is the natural cause. Overgrazing, deforestation, faulty agricultural practices, construction, and mining are some of the man-made causes that highly contribute to soil erosion.
Soil development and erosion occur simultaneously, and there is normally a balance between the two, but this balance is disturbed due to natural and human causes. There are various types of soil erosion like a sheet, gully, slope, rill, splash, and a few others. Soil erosion can be prevented by afforestation, terrace farming (for hilly regions), contour ploughing, strip cropping, and shelterbelts. Thus, Both (A)and (R) are true, but (R) is not the correct explanation of (A) because the simultaneous occurrence of soil formation and erosion is not the cause of soil erosion.
