Are deltas created by erosion or deposition?
Deltas are created by deposition. They form when sediment carried by a river is deposited as the river slows down and meets standing water, such as an ocean or lake. Erosion plays a role in shaping the delta, but the primary process involved in delta formation is deposition.
What do sediment deposits on dry land form?
Sediment deposits on dry land can form various landforms such as sand dunes, alluvial plains, and deltas. Over time, these deposits can accumulate and be cemented together to form sedimentary rocks.
What countries have deltas?
Some countries with deltas include Bangladesh (Ganges-Brahmaputra Delta), Egypt (Nile Delta), Vietnam (Mekong Delta), and Nigeria (Niger Delta). Deltas form where rivers meet the sea, depositing sediment to create fertile land and unique ecosystems.
What does deposition mean in science?
taking testimony outside of court
Where are deltas formed and why are they formed there?
Where a river which transmits a great deal of material arrives at the sea and there is little tidal range a delta will form. Example the Nile into the Mediterranean or the Mississippi into the Gulf of Mexico. The Amazon & the Congo, which flow into an Ocean, the Atlantic in these examples, do not form deltas because the ocean currents distribute the outflow of material into & along the ocean currents.
Where do deltas form?
Deltas form at the mouth of rivers.
Deltas form where?
Deltas form at the mouth of rivers.
What is deposit form?
Beaches or deltas
What shape does deltas form?
a curved line
How did the deltas form?
don;t care
What processes together form dunes and valleys and deltas?
Erosion and Depositionerosion causes dunes and valleysdepostion causes deltas
Where do river deltas usually form?
At the mouth of a river.
Where do deltas usually form?
At the mouth (opening/beginning) of a river.

What are two land-forms form by river deposition?
River deposition creates landforms such as alluvial and deltas.
How is a deltas formed?
Deltas form from erosion of rocks.The river must carry enough sediment to layer into deltas over time. The river's velocity decreases rapidly, causing it to deposit the majority.An alluvium builds up to form the river delta.A river delta is a landform that forms at the mouth of a river, where the river flows into an ocean, sea, estuary, lake, or reservoir. Deltas form from deposition of sediment carried by a river as the flow leaves its mouth.Deltas mostly form over long periods of time.
