Detailed explanation-1: -Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water. A similar process, weathering, breaks down or dissolves rock, but does not involve movement.
Detailed explanation-2: -Soil erosion occurs primarily when dirt is left exposed to strong winds, hard rains, and flowing water. In some cases, human activities, especially farming and land clearing, leave soil vulnerable to erosion.
Detailed explanation-3: -The wearing away of the earth’s surface is called erosion.
Detailed explanation-4: -Wind erosion is referred to as eolian erosion. Differences in atmospheric pressure will cause the motion of air that can erode surface material when velocities are high enough to move particles.
