Streams and Floods

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

Solution, suspension, and bed load are the three components of...

• stream load

• gravity

• erosion

• water

What scenario would you expect to find the most erosion due to runoff?

• A shallow slope covered with grass

• A shallow, bare slope

• A steep slope covered with evergreen trees

• A steep, bare slope

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

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
