Answer:
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 (more rarely) another river that cannot carry away the supplied sediment.
Explanation:
The definition of a delta is a triangle-shaped deposit of sand, clay or silt at the mouth of a river. An example of a delta is where the Nile River drains into the Mediterranean Sea. ... Deltas form when a river flows into a body of standing water, such as a sea or lake, and deposits large quantities of sediment.
