GEOLOGY

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: -Erosion is the physical removal and transportation of weathered material by water, wind, ice, or gravity.

Detailed explanation-3: -Sediment moves from one place to another through the process of erosion. Erosion is the removal and transportation of rock or soil. Erosion can move sediment through water, ice, or wind. Water can wash sediment, such as gravel or pebbles, down from a creek, into a river, and eventually to that river’s delta.

Detailed explanation-4: -Erosion is the process of carrying away or displacement of sediment by the action of wind, water, gravity, or ice (Smith & Smith 1998). The process of deposition of sediment from a state of suspension or solution in a fluid is called sedimentation (http://en.wikipedia.org/wiki/Sediment).

Detailed explanation-5: -This transport-and-deposition process of sediment is known as erosion. The act of breaking down monolithic material into smaller pieces is known as weathering. Weathering and erosion together are the two processes responsible for the movement of sediment across the globe.
