Ecosystems

An estuary is the mouth of a river or part of a river that is at sea level that has freshwater at low tides and salt water at high tides. They are usually enclosed and sometimes when water rushes in with the high tide it can create a tidal bore, or a wave, that will keep going until its energy is spent. The are also known as bays, lagoons, harbors, inlets, and sounds. An estuary is rich in plant life with many adaptations in order to survive the salty sea water. They also have a lot of bird life.
