What affects stream erosion?
There are three factors that affect stream erosion. These are water velocity, shape, size and depth of channel, and stream capacity to transport eroded materials.
Is a stream a result of erosion or deposition?
A stream, which flows in a channel, is formed as a result of erosion as the channel itself must be formed from erosion. Deposition is not common here, but there is a lot of loose material in the stream which is eroded over time, which has been put there through erosion. The material is first eroded further, then transported, and will ultimately be deposited at the mouth.
What is a stream that has channel with many curves?
A stream with a channel that has many curves is sometimes called a meander. This area often offers a large amount of erosion and damage to the surrounding land.
Where is the stream eroding the bank?
Stream Bank erosion is the wearing away of the banks of a stream or river. This is distinguished from erosion of the bed of the watercourse, which is referred to as scour. The roots of trees growing by a stream are undercut by such erosion. As the roots bind the soil tightly, they form abutments which jut out over the water. These have a significant effect upon the rate and progress of the erosion.
What is load and how does it affect erosion?
Stream Load is the amount of material a stream can hold as it flows. As a stream flows it causes erosion, and this erosion is carried about as material in the stream. As too much is eroded, the extra material will fall to the bottom, or push it's way to the sides.

This kind of alluvial fan forms where a stream empties into a lake?
This is water erosion that does not flow in a channel

What are the 3 factors that mifht influence how fast a stream would flow?
The gradient , the channel roughness, and the channel shape all effect the speed or velocity of stream flow
What is the difference between a young mature and old stream?
A young stream is typically characterized by a steep gradient, fast flow, and erosion of its channel. As a stream matures, it becomes more meandering, has a gentler gradient, and tends to deposit sediments in its channel. An old stream has a low gradient, meanders extensively, and has a stable floodplain with significant sediment deposition.
What term describes a path followed by a stream?
The path that a stream follows is a channel.
What is a bend or curve in a stream channel?
stream channel
The steepness or slope of a stream channel in the direction of flow is the channel's?
stream channel
What is the fastest form of erosion n?
stream erosion
There can be no stream erosion or glacial erosion without?
Wind
