What are the 4 types of estuaries?
Estuaries are typically classified by their existing geology or their geologic origins (in other words, how they were formed). The four major types of estuaries classified by their geology are drowned river valley, bar-built, tectonic, and fjords.
Where estuaries are located in the world?
Estuaries are found on the coast where fresh water like a river or a bay has access to the ocean. A good example of an estuary is a salt marsh that can be found close to the coast. Another example is when a river feeds directly into the ocean. The largest estuary in the United States is the Chesapeake Bay estuary.

What is a salt wedge?
Quick Reference. An intrusion of sea water into a tidal estuary in the form of a wedge along the bed of the estuary. The lighter fresh water from riverine sources overrides the denser salt water from marine sources unless mixing of the water masses is caused by estuarine topography.
What is a drowned river mouth?
In physical geography terms the Webster Dictionary (2nd edn) defines an estuary as: “a drowned river mouth, caused by the sinking of the land near the coast.” Stamp, in his Glossary of Geographical Terms (1966), defines an estuary as a “tidal opening, an inlet or creek through which the tide enters; an arm of the sea …

Are estuaries saltwater or freshwater?
An estuary is a partially enclosed, coastal water body where freshwater from rivers and streams mixes with salt water from the ocean. Estuaries, and their surrounding lands, are places of transition from land to sea.
How are estuaries created?
This has occurred as sediments are washed down the rivers, or carried in from the sea by the tide, and dropped in the more tranquil conditions of the estuary. … All are a result of marine transgression, the first being drowned river valleys, which are referred to as spit enclosed or funnel-shaped estuaries.
How many estuaries are in India?
7 Beautiful Estuaries in India.
What is a mix of salt and fresh water?
Brackish water, also sometimes termed brack water, is water occurring in a natural environment having more salinity than freshwater, but not as much as seawater. It may result from mixing seawater (salt water) with fresh water together, as in estuaries, or it may occur in brackish fossil aquifers.
What is Delta in geography?
Deltas are wetlands that form as rivers empty their water and sediment into another body of water. … Deltas are wetlands that form as rivers empty their water and sediment into another body of water, such as an ocean, lake, or another river. Although very uncommon, deltas can also empty into land.
