deposition
What is a narrow channel carved by surface runoff?
rill
As the current in a stream becomes stronger, what will happen to its erosional power?
it increases
Youthful rivers often have
rapids
The carrying capacity of a stream is its ___________.
ability to transport sediment
As the velocity of a stream decreases, what happens to the size particles that it is able to carry?
It's only able to carry smaller particles
The landscape feature labeled X is best described as
Floodplain
Higher velocity discharge (volume of water):
has bigger particles and more particles that flow through it.
______________________ is the amount of water a river or stream can carry in a given amount of time.
Discharge
What kind of river produces meanders like the ones in the image?
Old
The diagram below shows a portion of a stream. The sand bar formed as a direct result of
deposition due to a decrease in stream velocity
