Question

Give Reasons:

Silt deposits are less at estuaries than deltas.

Answer 1

1. Deltas form at the mouths of large rivers when sediments and silt accumulate.
2. As sediments continue to accumulate, the course of the river may even be changed.
3. Estuary is formed where the rivers meet the sea.
4. Deposition of silt by the river is not possible here in the estuaries like delta as if the waves keep on eroding the deposits.
