Question

What is a delta?how is delta formed​

Answer 1

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.

Answer 2

When a river reaches the sea, the fine material which has not yet dropped is deposited ani its mouth forming a delta. The work 'delta, is derived from a Greek alphabet.
