Lab: Modeling Water Erosion

Question 1

How did changing from a light drizzle to a downpour affect the river and the sediment in it? Check all that apply.The river increased its slope.The volume of the river decreased.The velocity of the river increased.There was more erosion in the stream.The type of sediment that moved changed.

Revolt · Accepted Answer

The velocity of the river increased.; There was more erosion in the stream.; The type of sediment that moved changed.
