Now suppose a stream has a high volume but a low gradient. how might the
stream change the land? provide your reasoning.

The stream has a high volume but a low gradient will run through small rocks and small valley. It slowly runs all over the area. Even though it is low gradient its volume is high so it craves the area and then it changes the land.

Explanation:

Low gradient streams are less forced but it is wider as it slowly flows through the land. As it is separated from the high gradient stream. Then it finds its path and creates it. It will slowly eradicate the soil or land or rock which present in its path. Day by day the flow of large quantity of water will change the position of the land. Before reaching the sea, it will cover up the river.
