what is the difference between a delta and the mouth of a river?
317165
As a river flows, it picks up sediment from the river bed, eroding banks, and debris on the water. The river mouth is where much of this gravel, sand, silt, and clay—called alluvium—is deposited. When large amounts of alluvium are deposited at the mouth of a river, a delta is formed.

A river delta is a landform created by deposition of sediment that is carried by a river as the flow leaves its mouth and enters slower-moving or stagnant water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, or (more rarely) another river that cannot carry away the supplied sediment.

Geography. Spanning some 150 km in width, the Red River Delta is located in the western coastal zone of the Gulf of Tonkin. The Red River is the second largest river in Vietnam and one of the five largest rivers on the East Asia coast.

Difference Between Ocean, Lakes and Rivers. ... Oceans are large bodies of saltwater surrounding a continent. A river is a large flowing water body that empties itself into the sea. Lakes are large water bodies that are surrounded by land on all sides.

Advantages. More expensive buildings and land uses are further away from the river, so have a reduced flood risk. Less damage is caused, leading to fewer insurance claims.

The difference between the two is that swamps usually have deeper standing water and are wet for longer periods of the year, according to the National Parks Service. Marshes have rich, waterlogged soils that support plant life, according to National Geographic.

The difference is basically slope. The shelf has a very shallow slope and extends out from the shoreline. The continental slope then comes next. The shelf is basically the area made up by sediment and the slope is where those sediment grains cascade downwards towards the abyssal plain.

However, some towns and cities have been built where two or more rivers meet, something known as a confluence. The joining of the two bodies of water creates a beautiful natural feature and often becomes an attraction in its own right.

A tributary is small streams or rivers that join to form a larger one. A delta is where a river ends and merges with a larger body of water.

EROSION: Wearing away the soil and rocks. This puts lots of sand, mud, pebbles and silt into the river. TRANSPORT: Moving material. The force of the flowing water moves the mud, sand, pebbles and silt created by erosion.

Answer Expert Verified. When a river reaches a lake or the sea the water slows down and loses the power to carry sediment . ... Some rivers drop so much sediment that waves and tides can't carry it all away. It builds up in layers forming a delta.

A river is a course of water that flows to another water source such as an ocean, lake or even another river. A river is not exactly a landform but part of other landforms such as mountains, prairies and valleys. They can even be parts of many different landforms at the same time.

Plants & animals. Dams are often constructed across rivers to store water that would naturally find its way to the lower reaches of the river and into the sea. ... The nature of the river flow downstream is changed. The dam can hold back sediment that normally finds its way downstream.

A sea is smaller than an ocean which may be partly or fully enclosed by land. A river is a naturally flowing body of water which comes from higher areas such as mountains. Seas are much bigger than rivers which are longer and narrower. Seas have salt water while rivers have fresh water.

Upper course river features include steep-sided V-shaped valleys, interlocking spurs, rapids, waterfalls and gorges. Middle course river features include wider, shallower valleys, meanders, and oxbow lakes. Lower course river features include wide flat-bottomed valleys, floodplains and deltas.

The difference in height between the high tide and the low tide is called the tidal range. A horizontal movement of water often accompanies the rising and falling of the tide. ... The incoming tide along the coast and into the bays and estuaries is called a flood current; the outgoing tide is called an ebb current.
