Question

how is a delta formed

Answer 1

$<b > hey dear$



When a river reaches a lake or the sea the water slows down and loses the power to carry sediment . The sediment is dropped at the mouth of the river. Some rivers drop so much sediment that waves and tides can't carry it all away. It builds up in layers forming a delta.

Answer 2

deltas are formed by the sedimendation of debris and rock on the end or the mouth of the river .
