Water erosion occurs when moving water carries away bits of rock and dirt. There are four types of water erosion: sheet erosion, rill erosion, gully erosion and bank erosion. All of these depend on the type of land being moved by water. This type of erosion creates valleys, canyons, shorelines and cliffs.


Water erosion comes in several different forms with various causes. No matter the differences, we humans can have a large impact on our water quality and erosion rates. While the causes of erosion by water are generally natural, we can play a large role in reducing water erosion, and preventing water pollution. Water erosion is usually caused ...


In earth science, erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location (not to be confused with weathering which involves no movement). This natural process is caused by the dynamic activity of erosive agents, that is, water, ice (glaciers), snow ...


Water is the most important erosional agent and erodes most commonly as running water in streams. However, water in all its forms is erosional. Raindrops (especially in dry environments) create splash erosion that moves tiny particles of soil.


Groundwater is underground water that helps shape the land. When it rains not all rain water becomes runoff, it also can be soaked into the ground. Once the water is soaked up it fills in the cracks of soil and rock. Groundwater can sometimes cause erosion through processes of chemical weathering.


Most erosion is performed by liquid water, wind, or ice (usually in the form of a glacier).If the wind is dusty, or water or glacial ice is muddy, erosion is taking place. The brown color indicates that bits of rock and soil are suspended in the fluid (air or water) and being transported from one place to another. This transported material is called sediment.


erosion (ĭrō`zhən), general term for the processes by which the surface of the earth is constantly being worn away.The principal agents are gravity, running water, near-shore waves, ice (mostly glaciers), and wind. All running water gathers and transports particles of soil or fragments of rock (formed by weathering weathering, collective term for the processes by which rock at or near the ...


Groundwater can cause erosion through chemical weathering. First, water that sinks into the ground mixes with carbon dioxide to form carbonic acid, a weak acid. Carbonic acid can break down limestone. Some of the limestone changes chemically and is carried away in a solution of water. This gradually hollows out pockets in the rock.


Water and wind can cause erosion the a variety of ways, but the overall answer is friction. Water can cause erosion by a) liquid water beating a way at the rock and slowly carving into it over a ...


Water erosion. Moving water is the most important natural erosional agent. The wastage of the sea coast, or coastal erosion, is brought about mainly by the action of sea waves but also, in part, by the disintegration or degradation of sea cliffs by atmospheric agents such as rain, frost, and tidal scour.
