Question

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.

Explanation:

When changing from a light drizzle to a downpour, more water enters the river, increasing its volume. This leads to an increase in velocity. Higher - velocity water has more erosive power, causing more erosion in the stream. Also, the increased force can move different types of sediment. The slope of the river is determined by the landscape and not by rainfall intensity, and an increase in rainfall leads to an increase in river volume, not a decrease.

Answer:

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