Detailed explanation-1: -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.

Detailed explanation-2: -Encyclopedic Entry Vocabulary. Deltas are wetlands that form as rivers empty their water and sediment into another body of water, such as an ocean, lake, or another river. Although very uncommon, deltas can also empty into land. A river moves more slowly as it nears its mouth, or end.

Detailed explanation-3: -A delta is a landform created by the deposition of sediments that is carried by a river as the flow leaves its mouth and enters slow-moving or stagnant water. This is usually formed when the river meets the ocean. Deltas are very fertile. Suggest Corrections.

Detailed explanation-4: -A river delta is a landform created by deposition of sediment that is carried by a river as the flow leaves its mouth and enters slower-moving or stagnant water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, or another river that cannot carry away the supplied sediment.

Detailed explanation-5: -Estuaries are stretches where rivers approach the ocean. They are influenced by freshwater from upstream as well as the influx of saltwater from rising tides. Deltas are areas near the mouth of a river or estuary, where these moving bodies of water deposit large amounts of sediment.
