There are 4 main processes of erosion:
1) Hydraulic action: The sheer force of the river water removes loose material from the bed and banks of the river. It is most effective on the banks and can lead to undercutting and collapse.
2) Corrasion (not corrosion) / abrasion: This is the wearing away of the bed and banks by the river's load. The load can vary from small particles of clay and sand to large boulders. This is the main type of erosion in most rivers.
3) Attrition: When pieces of rock are broken away form the bed and banks, the edges are usually sharp. However, in swirling water rocks and stones collide with each other and with the bed and banks. Over time the sharp edges become smooth and the pieces of rock become smaller in size.
4) Solution: Some rocks, such as limestone, dissolve slowly in river water which contains dissolved carbon dioxide from the air.

∙ 9y agoErosion wears away the land near a river. Water erosion is responsible for moving sediment around to different places, which can change the landscape.

What does erosion carry away?
Erosion carries away sediment.
How is wind erosion different from water and glacier erosion?
Wind does not carry heavy objects.
What kind of soil erosion takes place on river banks?
The type of soil erosion that takes place mostly at river banks is sheet erosion, its caused by hydraulic action of water against the adjacent land. In some cases where the power of the river is great Gully Erosion could develop.
What are five landforms formed by river erosion?
Through erosion, a river creates valleys, waterfalls, flood plains, meanders, and oxbow lakes.
Where does deposition occur in a river?
deposition occurs at the part of a river where there is no longer enough energy for the water to carry the sediments and they are deposited. Deposition is when an agent or erosion (in this case river water) loses energy and can no longer carry sediments, so it deposits them.
What is the work of a river?
The work of the river as an agent of erosion and deposition is that it carries away the soil from one point to another. At a level ground, the sand deposits at the bottom of the river bed.
How does erosion effect Mississippi River?
Erosion effects the Mississippi river by causing collapse in the banks of the river. Erosion also causes the river to change course slightly as the banks change.
Why is the work of erosion and transportation of a river more in mountains than in plains?
The work of erosion and transportation is more in the mountains than in the plains because a river flows very fast in the highlands, leaving more scope to deposit water and finally cause erosion. But in the tables, the flow of the river is slower. It leaves less scope for water deposit and thus results in less deterioration.
When a river carries away rock particles this is known as the process of?
Erosion by moving water in a river is called fluvial erosion.
What does erosion carry away?
Erosion carries away sediment.
Is it erosion or weathering that widens a river's bank?
It is erosion by flowing water, especially when the river is in spate, that can widen the river's banks.
Is a river erosion faster than a wave erosion?
It depends how fast the wave and river speed are.
Was the Arkansas River Valley formed by erosion or depostion?
The Arkansas River was formed by erosion, not deposition.
What type of erosion was the Grand Canyon formed by?
Well it was formed by the Colorado river! Which is water erosion!
What kind of erosion can affect a river valley?
Water erosion
Why does a river deposits its load?
the 3 ways are:1) solution2)suspension3)bed load
What is vertical erosion?
Vertical erosion is when the depth of the river is greater than the width causing erosion to take place on the bed of the river. This is also when lots of water enters the river but not as much is exiting it.
