Q. As the river approaches the sea, the speed of the flowing water decreases and the river begins to break up into a number of streams called ____.
Answer: Distributaries
Notes: As the river approaches the sea, the speed of the flowing water decreases, and the river begins to break up into several streams known as distributaries. Then a time comes when the river becomes very slow and it begins to deposit its load. Each distributary forms its own mouth. The collection of sediments from all the mouths forms a delta, which is a triangular landmass.
