Question

How will you differentiate between a roll, gully, stream and river

Answer 1

Answer:

Explanation:

A rill is a shallow channel cut into soil by the erosive action of flowing water , the similar but smaller channels are called microrills and the larger channels are called gully , gullies and rills both are formed when water concentrates in narrow run-off paths and channels (erosive flowing)

A river is a natural flow or path that follows  a well-defined and permanent path , usually within a valley whereas a stream (aka brook or creak) that follows a more temporary path , a river is much longer and deeper than a stream
