A delta is a landform where the mouth of a river flows into an ocean, sea, desert, estuary, lake or another river . It builds up sediment outwards into the flat area which the river 's flow encounters (as a deltaic deposit) transported by the water and set down as the currents slow. Deltaic deposits of larger, heavily-laden rivers are characterized by the main channel dividing amongst often substantial land masses into multiple streams known as distributaries. These divide and come together again to form a maze of active and inactive channels. This hydrogeologic formation is known as an alluvial fan. The deposit at the mouth of a river is usually roughly triangular in shape. The triangular shape and the increased width at the base are due to blocking of the river mouth, with resulting continual formation of distributaries at angles to the original course. These distributaries start out flowing fairly fast, but slow as more sediment is deposited and ultimately, the water flows elsewhere. This change in flow affects the particle size in the suspended and bed loads, the size of the particles decrease as the flow slows and the larger particles are deposited. This deposition goes on continually in a cyclic fashion, creating alternating sediment beds of coarse and fine grain deposits. Herodotus the great historian used this term for the Nile river delta because the sediment deposit at its mouth had the shape of upper-case Greek letter Delta : Δ.
What else can I help you with?
Sediments deposited where a river flows into an ocean or lake form a(n)?
it is a delta
What are sediments deposited where a river flows into an ocean or lake called?
it falls into the ocean and doesn't form anything
What is a large stream of water that flows into a lake or ocean or other body of water?
A river delta, which are usually very lush environments, like the Nile River Delta in Egypt.
Why does a delta form often where a river empties into the ocean?
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.

Sediments form a where the river meets the ocean?
The sediments are called silt or alluvium. The land formed from these sedimants where the river meets the ocean is a delta.
How does Delta form?
As a river flows it picks up sediment and carries it away. When the river reaches the ocean the sediments deposited, over time a delta forms.
Why does delta often form where a river meets the ocean?
Because water slows down and sediment drops to the bottom
Why does a delta form where the river meets the ocean?
the water slows down, causing the sediment to sink
What is a land form that forms when a river slows down as it flows into an ocean or lake?
That is called a delta.
What is found at the mouth of a river?
A sea or ocean is found at the mouth of a river.
A large amount of sediments deposited at the mouth of a river form what?
A large amount of sediments deposited at the mouth of a river can form a delta. Deltas are landforms created by the accumulation of sediments carried by the river and deposited as the river's flow slows upon entering a body of water, such as a lake or ocean.
