GENERAL KNOWLEDGE

Detailed explanation-1: -An estuary is an area where a freshwater river or stream meets the ocean. When freshwater and seawater combine, the water becomes brackish, or slightly salty.

Detailed explanation-2: -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.

Detailed explanation-3: -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.

Detailed explanation-4: -The Chesapeake Bay in Maryland is a large estuary. The bays surrounding the boroughs of New York City are also estuaries. San Francisco Bay in California and Lake Pontchartrain in Louisiana are other examples of large, developed estuaries.
