Because the river water is no longer flowing downhill, the water slows down.
A delta forms at the point where a river meets the ocean. As river water flows into the ocean, the water slows and sand and silt particles are deposited. This forms the fan-shaped landmass under the water known as a delta.
A delta is a landform that forms at the mouth of a river where it meets a body of water, such as a sea or ocean.
The sediments are called silt or alluvium. The land formed from these sedimants where the river meets the ocean is a delta.

Deltas form where rivers meet the ocean because the river's sediment load slows down and settles due to the decrease in water velocity caused by the ocean's tidal movements and waves. This accumulation of sediment creates landforms with various distributary channels that fan out like the Greek letter delta, giving rise to the name.
