Glossary of geography terms Delta: A delta is a land form at the mouth of a river where the main stream splits up into several distributaries. It is formed from the deposition of the sediment carried by the river as the flow leaves the mouth of the river.

Rivers: From Source to Sea The transition between river and ocean, bay or lake is known as a delta. Most rivers have a delta, an area where the river divides into many channels and river water mixes with sea or lake water as the river water reaches the end of its journey.A famous example of a delta is where the Nile River meets the Mediterranean Sea in Egypt, called the Nile Delta.he two streams meet at a confluence. It takes many tributary streams to form a river. A river grows larger as it collects water from more tributaries. Streams usually form rivers in the higher elevations of mountains and hills.

Deltas Some deltas are so large that people can live on them. The Nile delta is a very important farming area in Egypt. Deltas have a fairly flat section called a delta plain that is above water. The river cuts many small channels through the delta plain. These channels are called distributaries. New sections of delta build up at the mouths of the distributaries.

Geography Geography (from Greek γεωγραφία, geographia, lit. earth description) is a field study of the lands, the features, the inhabitants, and the phenomena of Earth. A literal translation would be to describe or picture or write about the earth.The first person to use the word geography was Eratosthenes (276–194 BC).uman geography is a branch of geography that focuses on the study of patterns and processes that shape the human society. It encompasses the human, political, cultural, social, and economic aspects.

- A delta forms if the waves and the tide cannot carry all of the material away. Formation of a delta: A river carrying sediment reaches the sea or a lake. It loses energy and deposits material. The sediment may be sorted as the heaviest material is deposited first.

River delta A river delta is a landform that forms from deposition of sediment carried by a river as the flow leaves its mouth and enters slower-moving or standing water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, or (more rarely) another river that cannot transport away the supplied sediment.Despite a popular legend, this use of the word delta was not coined by Herodotus.he tidal currents also cannot be too strong, as sediment would wash out into the water body faster than the river deposits it. Of course, the river must carry enough sediment to layer into deltas over time. The river's velocity decreases rapidly, causing it to deposit the majority, if not all, of its load.

Delta Deltas have long played an important role in human history. These fertile areas where rivers flow into large bodies of water have served as fishing, farming, and living sites. Of the great deltas around the world, perhaps none has had a greater role in civilization than the delta of Egypt's Nile River.

River Delta River deltas form when a river carrying sediment reaches either (1) a body of water, such as a lake, ocean, or reservoir, (2) another river that cannot remove the sediment quickly enough to stop delta formation, or (3) an inland region where the water spreads out and deposits sediments.

River delta A river delta is a landform that forms from deposition of sediment carried by a river as the flow leaves its mouth and enters slower-moving or standing water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, or (more rarely) another river that cannot transport away the supplied sediment. River deltas are ecologically important as they provide coastline defense, are home to many species, and can impact drinking water supply.

Ten Geographical Landforms in the US The biggest delta in the United States is the Mississippi Delta, where sediment has collected as the water of the Mississippi empties into the Gulf of Mexico. The delta is fan-shaped, creating a visual triangle. It is called delta because it is similar in shape to the Greek letter delta.

Mississippi River Delta The Mississippi River Delta is not to be confused with the Mississippi Delta region, an alluvial plain located some 300 miles (480 km) northward in western Mississippi along the Mississippi River.he delta is a vital stopping point along the Mississippi Flyway. The flyway stretches from southern Ontario to the mouth of the Mississippi River and contains one of the longest migration routes in the Western Hemisphere.

Geography of River Deltas The upper delta plain is the area nearest to the land. It is usually the area with the least water and highest elevation. The subaqueous delta is the portion of the delta that is closest to the sea or body of water into which the river flows. This area is usually past the shoreline and it is below water level.

Deltas Deltas have a fairly flat section called a delta plain that is above water. The river cuts many small channels through the delta plain. These channels are called distributaries. New sections of delta build up at the mouths of the distributaries. The rest of the delta is under water . There is a steeply sloping delta front that faces the lake or ocean. The prodelta is furthest away from the mouth of the river and is deepest under water. Click to view larger and see the legend. Limit of tidal inundation.

In a tidal delta, new distributaries are formed during times when there's a lot of water around – such as floods or storm surges. These distributaries slowly silt up at a pretty constant rate until they fizzle out.

- Passionate about all things Australian. A river delta is the landform occurring at the river mouth, where the river meets the sea. It is largely a result of the silt brought down by the river system. The river spreads out in a fan shape into many channels called distributaries, which form outlets and islands.t is a landform that is created at the mouth of a river where that river flows into an ocean, sea, estuary, lake, reservoir or another river.

What is the difference between a river basin and delta region? Best Answer: River Basins A river basin is an area of land drained by a river and its tributaries. River basins have typical features, these include: Tributaries-smaller rivers flowing into a larger river.A Watershed-an area of highland surrounding the river basin. A confluence-where a river joins another river.ource-the start of a river. Mouth-Where a river meets a lake, the sea or an ocean. DELTA: A delta is a landform that is formed at the mouth of a river, where that river flows into an ocean, sea, estuary, lake, or reservoir.
