Erosion is the process of soil, rock, and other materials being carried away by natural agents like wind, water, and ice. Deposition is the process of those materials being dropped off in a new location by those same natural agents. Erosion wears away land over time, while deposition builds up new landforms. ( 13 votes)
Physical processes Rainfall and surface runoff Soil and water being splashed by the impact of a single raindrop. Rainfall, and the surface runoff which may result from rainfall, produces four main types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion.Splash erosion is generally seen as the first and least severe stage in the soil erosion process, which is ...
Mechanical weathering is the creation of sediment through physical means. For example, a stream can dislodge soil particles from its banks. Chemical weathering is the creation of sediment through chemical means. For example, acid rain can react with rocks, dissolving them. Erosion occurs when water transports sediment from one place to another.
Hydraulic action is one of four main types of erosion, the others being abrasion, attrition, and solution. While hydraulic action involves the force of water, abrasion and attrition involve the physical wearing down of rocks, and solution involves the dissolution of certain types of rock in water.

So, water erosion is the detachment and transport of soil material by water. This process could be natural or facilitated by human activity. For example, when humans cut down too many trees and plants, the soil remains bare and loose and hence more easily moved by water. Water erosion wears away the surface of the earth.
Water wears away rocks, and can dissolve them. When water seeps into cracks on a rock, it freezes, and gets bigger, causing the rock to push out. Erosion is simply the transportation of weathered, or broken down, materials. Wind, water and ice can erode, and so can movements from the earth. Water can carry the broken down rocks, and so can wind.
