what do floodplains,sandbars and river deltas have in common?

Explanation:

A floodplain is defined as "a relatively flat strip of land, next to a river and that overflows the waters during floods".

A sandbank is the accumulation of sand or gravel along the shoreline or in a riverbed.

A fluvial delta, therefore, is a triangular territory that forms at the mouth of a river through the sediments deposited by the current.

They have in common that all three develop in the rivers.

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.
