Question

Melting ice and snow from mountains act as ________ for many rivers and streams.

Answer 1

I think outlets or obstacles for many rivers and streams

Answer 2

Streams.

There are many rivers that begin their life as a tiny stream while running down from a mountain slope.

They are then fed by rainwater that flows off the land.

The water then follows cracks and crevices in the land when it flows through the downhill.

There are small streams that meet and join with each other and become larger till the flow becomes a river.

On the way down, a water body shapes the landscape flowing away rocks and making a group of valleys.
