Detailed explanation-1: -An estuary is a partially enclosed, coastal water body where freshwater from rivers and streams mixes with salt water from the ocean.
Detailed explanation-2: -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-3: -Estuaries can filter out sediments and pollutants from rivers and streams before they flow into the ocean. As water runs off the land, plants such as marsh vegetation and seagrasses absorb and filter out pollution. This provides cleaner water for humans and marine life.
Detailed explanation-4: -Estuaries are very productive ecosystems because they constantly receive fresh nutrients from the river.
