Delta formed at the mouth of the river (give reason) |
|
Answer» When large amounts of alluvium are deposited at the mouth of a river, a delta is formed. The river slows down at the mouth, so it doesn't have the energy to CARRY all the silt, sand, and clay ANYMORE. These sediments form the flat, usually triangle-shaped land of a delta.Explanation:The tidal currents also cannot be too strong, as sediment would wash out into the WATER BODY faster than the river deposits it. The river must carry enough sediment to layer into DELTAS over time. ... This alluvium builds up to form the river delta.As soon as river water comes in contact with sea water coagulate the suspended colloidal particles which ultimately settle down at the point of contact. |
