Base your answers on the diagram and data table below. The diagram shows the equipment used to determine the factors affecting the rate of erosion in a stream. The data table shows the time it took a 10-gram sample of quartz sand to move 100 centimeters down the rain gutter under various conditions.
What is the relationship between the water velocity and the rate of erosion?
(1 point)
Responses
If the water velocity increases, the rate of erosion increases.
If the water velocity remains constant, the rate of erosion increases.
If the water velocity remains constant, the rate of erosion decreases.
If the water velocity decreases, the rate of erosion increases
Question 2
In this experiment, the water velocity could be increased by(1 point)
Responses
lowering the flexible hose
increasing the amount of water from the faucet
decreasing the slope of the rain gutter
widening the rain gutter
The correct answer for question 1 is: If the water velocity increases, the rate of erosion increases.
The correct answer for question 2 is: increasing the amount of water from the faucet.
