Because the river water is no longer flowing downhill, the water slows down.
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.
A river delta, which are usually very lush environments, like the Nile River Delta in Egypt.
Because water slows down and sediment drops to the bottom
A river ends its journy when it flows into a body of water such as a ocean or lake. Because the river water, such as an ocean or lake. Because the river water is no longer flowing downhill, the water slows down. Which makes sediment drop to the bottom. Sediment deposited where a river flows into into an ocean or lake builds upa landform called delta.
A delta. Deltas are landforms created by the deposition of sediment carried by a river as it enters a larger body of water such as an ocean. The sediment accumulates at the river's mouth, building up and forming a flat, often triangular-shaped landform.
Waterways from a fan-shaped area of fertile marshland.
When a river empties into a larger body of water it forms a triangle shaped area of mud, sand, and silt known as a delta. This area often has tall grasses, a marshy landscape and many small waterways leading to the ocean.

A river delta is an extension of a river's mouth, where the faster flowing water from a river, suddenly slows when it reaches an open body of water (e.g. a lake) and so deposits the suspended sediments in a zone around the mouth, causing an elevated river bar. Often you can see these from satellite images (google 'Indus River Delta') and is clearly identifiable as an elevation near the mouth of a river. This raised area is known as the delta. This is an explanation of a delta (not a definition). It is your job to define it in your own words however you think best. I hope that helps though :)
We call this a delta since it is somewhat shaped liked a D or triangle.
