      Distinguish between a tributary and a distributary.

    Answer:

                      A tributary is a stream which flows into a main stream (or parent) river. A tributary does not flow directly into a sea, ocean or lake.  Tributaries  and the main stream river drain the surrounding drainage basin of its surface water and groundwater. The reverse to a tributary is a distributary, a river that branches off and flows away from the main stream. The Yamuna is a tributary of the Ganga, whereas the Hugli is a distributary of the Ganga.
