Erosion and Deposition Practice Questions

The streambank on the outside of this meander is steeper than the streambank on the inside of this meander because the water on the outside of this meander is moving

• slower, causing more deposition
• slower, causing more erosion
• faster, causing more deposition
• faster, causing more erosion

Which table indicates where the greatest stream velocity and the greatest rate of stream erosion occur?

• 
• 
• 
• 

Based on the cross section, which map of a meandering stream best shows the positions of points X and Y?

• 
• 
• 
• 

Sediment is deposited in a river delta because the

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

What is the relationship between the water velocity and the rate of erosion?

• If the water velocity decreases, the rate of erosion increases.
• If the water velocity increases, the rate of erosion increases.
• If the water velocity remains constant, the rate of erosion decreases.
• If the water velocity remains constant, the rate of erosion increases.

Which graph best represents the correct relationship between the discharge of a river and the particle size that can be transported by that river?

• 
• 
• 
• 

What is the name of the stream feature forming at location X?

• V-shaped valley
• meander
• delta
• floodplain

Placing a second block under location A will cause the stream’s velocity to:

• decrease and the rate of erosion to decrease
• decrease and the rate of erosion to increase
• increase and the rate of erosion to decrease
• increase and the rate of erosion to increase
