Detailed explanation-1: -Liquid water is the major agent of erosion on Earth. Rain, rivers, floods, lakes, and the ocean carry away bits of soil and sand and slowly wash away the sediment. Rainfall produces four types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion.

Detailed explanation-2: -Water erosion is caused by the detachment and transport of soil by rainfall, runoff, melting snow or ice, and irrigation. Excessive erosion can threaten the production of agricultural and forest products.

Detailed explanation-3: -Basically, there are two main causes of soil erosion – wind and water. When the topmost layer of the soil is loose, it becomes vulnerable to the natural forces of wind and water to blow the soil particle away. This loss of topsoil particles is soil erosion, as it is an almost irreversible loss.

Detailed explanation-4: -Gully erosion happens when runoff concentrates and flows strongly enough to detach and move soil particles. For example, a waterfall may form, with runoff picking up energy as it plunges over the gully head. Splashback at the base of the gully head erodes the subsoil and the gully eats its way up the slope.

Detailed explanation-5: -Water. Water is the most common cause of soil erosion. Wind. Wind can also make soil erode by displacing it. Ice. We don’t get much ice here in Lawrenceville, GA, but for those that do, the concept is the same as water. Gravity. Gravity is a primary culprit behind the three other causes. 10-Dec-2020
