15 Questions
What are alluvial channels composed of?
Alluvial channels are composed of loose sediments, or alluvium.
What are the two types of alluvial channels?
The two types of alluvial channels are meandering channels and braided channels.
What causes the erosion of sediment chunks from the banks of the channel?
The fast water flow causes the erosion of sediment chunks from the banks of the channel.
What process is responsible for the settling of sediments in slow water flow?
The process responsible for the settling of sediments in slow water flow is deposition.
How do alluvial channels change their shape or course over time?
Alluvial channels change their shape or course over time through the processes of erosion and deposition.
What is the focus of this lesson?
The focus of this lesson is on the different types and characteristics of alluvial channels.
What path would water take if it encountered a 'Y' in the road?
Water would take the path of least resistance, the easy path.

What causes erosion on the outer bend of a meandering channel?
faster water flow
What is a cut bank?
a small cliff on the outer bank of the channel caused by erosion
What is a point bar?
a collection of sediment materials along the inner curve of the channel caused by deposition
What is a meander cutoff?
two bends joined by a new channel
What is an oxbow lake?
a free-standing and crescent-shaped body of water formed by a meander cutoff
What is a braided channel?
a network of small, interwoven channels separated by bars of deposited sediment
