Estuaries
Estuaries
Estuaries (pronunciation: /ˈestʃuˌeriz/) are partially enclosed coastal bodies of water where freshwater from rivers and streams mixes with saltwater from the sea. The term originates from the Latin word aestuarium, meaning tidal inlet.
Description
Estuaries are characterized by their unique brackish water conditions, which are a result of the mixing of freshwater and saltwater. This creates a diverse and productive ecosystem that supports a wide variety of plant and animal species.
Types of Estuaries
There are four main types of estuaries, classified based on their geology: coastal plain estuaries, tectonic estuaries, bar-built estuaries, and fjord estuaries.
Importance of Estuaries
Estuaries play a crucial role in the environment. They act as natural water filters, removing pollutants from the water. They also provide a safe habitat for many species of wildlife, and serve as nurseries for many species of fish and shellfish.
Threats to Estuaries
Estuaries face several threats, including pollution, climate change, and habitat destruction. These threats can have significant impacts on the health and diversity of the estuary ecosystem.
