Detailed explanation-1: -Sediment is solid material that is moved around by natural processes, like wind, water, ice, or gravity. This solid material is then deposited in a new location. This transport-and-deposition process of sediment is known as erosion.

Detailed explanation-2: -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).
