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.

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.
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 are two landforms formed by river erosion?
A rive cliff and a river deposit
What are the five landforms formed by river erosion?
stream,river,ocean and a lake..
What are five landforms formed by river erosion?
River valleys: V-shaped valleys created by the erosive action of flowing water. Meanders: Curving bends in a river formed by lateral erosion. Oxbow lakes: U-shaped bodies of water formed when a meander is cut off from the main river channel. River cliffs: Steep, exposed banks along the edge of a river created by erosion. River deltas: Triangular landforms at the mouth of a river formed by deposition of sediments carried by the river.
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.
What are some effective strategies for implementing low-cost river bank erosion control work?
Some effective strategies for implementing low-cost river bank erosion control work include planting vegetation along the river banks to stabilize the soil, using erosion control blankets or mats to prevent soil erosion, and installing rock or gabion structures to protect the banks from erosion. Regular monitoring and maintenance of these measures are also important to ensure their effectiveness in controlling erosion.
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.
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.
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.
Was the Arkansas River Valley formed by erosion or depostion?
The Arkansas River was formed by erosion, not deposition.
Is a river erosion faster than a wave erosion?
It depends how fast the wave and river speed are.
Why does a river deposits its load?
the 3 ways are:1) solution2)suspension3)bed load
What type of erosion was the Grand Canyon formed by?
Well it was formed by the Colorado river! Which is water erosion!
How does rivers cause erosion?
water in a river is constantly moving. Moving water will pick up sediments from the bottom of a river, and carry them with it. Water also has the power to move large rocks slowly along the bottom of a river.
What kind of erosion can affect a river valley?
Water erosion
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.
