Explanation: 

Detailed explanation-1: -An estuary is an area where a freshwater river or stream meets the ocean. In estuaries, the salty ocean mixes with a freshwater river, resulting in brackish water. Brackish water is somewhat salty, but not as salty as the ocean. An estuary may also be called a bay, lagoon, sound, or slough.

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 and their surrounding wetlands are bodies of water usually found where rivers meet the sea. Estuaries are home to unique plant and animal communities that have adapted to brackish water-a mixture of fresh water draining from the land and salty seawater.

Detailed explanation-4: -The four major types of estuaries classified by their geology are drowned river valley, bar-built, tectonic, and fjords.

Detailed explanation-5: -An estuary is an enclosed water region where freshwater from the lakes and streams mixes with the saltwater from the ocean. An estuary is a transition zone from the river to the ocean or maritime ecosystem.
