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: -The whole process of land formation is called EROSION. Erosion is the wearing away of the Earth’s surface by the act of natural forces. These are wind, water andd air. The soil and the rock are moved from one location to the other.
Detailed explanation-3: -The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.
