Question

What force causes the shape of streams and rivers in a watershed?

Answer 1

Answer:

gravity

Explanation:

streams erode dirt and rocks, transport the sediment, and redeposit it in new locations shaping the earths surface into a system of stream valleys. streams now flow downhill due to the force of gravity

Answer 2

That would be C, gravity.

Gravity moves many things, right now we have gravity pushing us down! Gravity can move things, so that would make the most sense.
