give a reason for the following:
1. Why Distributaries are formed when a river reaches near its mouth?

Answer 1

Answer:

river delta is a landform that forms from the deposition of sediment carried by a river as the flow leaves its mouth and enters slower-moving or stagnant water. ... The deposition of river's sediment at the mouth of the river in a large amount allows the river to form distrubutaries.

Answer 2

Answer:

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 distributaries. The river becomes so slow that it begins to deposit its load. Each distributary forms its own mouth. The collection of sediments from all the mouths forms a delta.
