Stream Erosion Cut Bank

What is a floodplain?

• The area near a river that floods when water levels get to be too high.

• The area near a river that looks boring or dull.

• The process of water levels going over a river or stream bank.

• Water gathering on the surface of the Earth because it doesn't seep into the ground.

The gradual movement or removal of sediment from a location by water is called...

• erosion

• runoff

• slope

• tributary

With a steeper slope, we would expect to see...

• less erosion

• more erosion

• the same amount of erosion

• no erosion at all

Which of the following statements is not true?

• Water causes more erosion on slopes without plants
• Water flows from higher to lower ground
• Faster water erodes more sediment
• As water slows, smaller particles are deposited first

When a stream or river starts to slow down, it:

• Picks up more sediment
• Erodes more rapidly
• Deposits fine sediments, but continues carrying larger rocks
• Deposits larger rocks, but continues carrying finer sediment

The steeper the slope, the ________ the stream.

• Slower
• Broader
• Faster
• Curvier

Which of these are traits of a stream’s floodplain? Select all that apply

• It is nutrient poor

• Is broader and deeper than its channel

• Is where the stream deposits much of its sediment load

• its elevation is usually higher than the river bed

The diagram below shows a portion of a stream. The sand bar formed as a direct result of 

• erosion due to a decrease in stream velocity 
• erosion due to an increase in stream velocity
• deposition due to a decrease in stream velocity
• deposition due to an increase in stream velocity 

Sediments are deposited in a river delta because the 

• velocity of the river decreased
• force of gravity decreased
• volume of the river increases
• gradient of the river increases

At which location is the greatest amount of sediment most likely being deposited?

• A
• B
• C
• D
