The rocks found at the bottom of a river smooth and flat because those are collides with each other.

Explanation:

At the bottom of the river, the rocks which are found are very smooth and the shape of these rocks are flat because the rocks at the bottom collide with each other.

This results in the chipping off parts of the rocks and this results in the surface of the rock to become smooth and becoming flat. Moreover the sand found at the bottom acts as a sand paper creating resistance and smooth-ens the rocks at the bottom of the river.

The River.

I think that they become smooth and flat as time goes. I think this because the river moves. The River is so powerful and harsh that it ends up smoothing out the rock.

Ex. You take a star shaped lollipop. You eat and lick this lollipop. Over time the candy will turn into a smoother and smaller shape and less pointy.

The River is the cause of how the rocks become smooth and flat.
