What does an estuary provide?

Answer 1

An estuary is the wide part of a river where it nears the sea. It can be formed by many reasons. One of them is rising sea levels. Due to higher sea levels, river valleys were flooded and thus forming drowned river valley or coastal plain estuaries. Secondly, the movement of sand and the formation of sandbars can enclose bodies of water along the coastline and form lagoon-type or bar-built estuaries. Also, we have estuaries formed by glacial processes. In colder climates, glaciers cut deep valleys in the landscape. When glaciers recede during warmer climate periods, coastal waters fill the valley to form fjord-type estuaries. Lastly, tectonic processes such as earthquakes and faulting also play a part in the formation of estuaries. This may cause the rapid sinking of coastal areas below sea level to form tectonically produced estuaries.

Answer 2

An estuary provides vital habitat for various species of fish, birds, and other wildlife. It also serves as a nursery for many marine species, helping to support biodiversity and maintain healthy ecosystems. Additionally, estuaries play a crucial role in filtering pollutants and improving water quality before it flows into the open ocean.

Answer 3

they are expanding tidal mouths of rivers
Usually defined as where a river enters the sea, but a similar feature may be found much less commonly, on a lake shore.

An Estuary (estuarine as an adjective) is formed where a small (even tiny) river enters a body of water that has an ebb and flow. At ocean edge this ebb and flow is provided by the tides, but on a lake shore, the process is much slower and relies on the seasonal rise and fall of the lake. Particularly if the lake has little sediment.

An estuarine environment may be an erosion environment, if the supply of silt down the river is less than that removed in the drainage phase of water movement. If the supply of silt is great, then coastal lagoons may be formed, though these will depend on silt transport along the coast as well.

Estuaries are a particularly rich ecosystem with their shallow warm waters, and adequate supply of water and nutrient.

Answer 4

Estuaries are formed when freshwater from streams and rivers mix with the seawater. The four types of estuaries are fjords, coastal plain estuaries, tectonic estuaries and bar-built estuaries.

Answer 5

Estuaries are low-lying coastal areas around rivers or streams. They contain a mix of salt water and fresh water and often contain buildup of sediment.

Answer 6

during the last interglacial period, the retreating of glaciers created massive valleys. When these glaciers melted the water filled up the valleys and thus created the first estuaries

Answer 7

I think estuaries provide habitats. There is a 90% chance I'm right.

Answer 8

what is an ecological function of an estuary?? i need a reply in the next fifteen or twenty minutes. thank you very much. -m

Answer 9

An estuary is a place where saltwater and freshwater meet and combine.

Answer 10

Galveston Bay and the Chesapeake Bay are both estuaries.
