Do you think the processes that form and shape the small stream bed are similar to those that form and shape the Grand Canyon? Why or why not?

Yes.

Explanation:

The processes that formed the small stream bed are similar to those that formed the Grand Canyon because both are formed by the flowing of river. The river flow through these regions and with this flow they takes rock particles with itself and makes several shapes and structures of that region. So we say that rivers and streams are responsible for the formation of  stream bed and Grand Canyon.
