The secret life of estuaries

The secret life of estuaries

The main idea of this text is to tell you that an estuary is the tidal mouth of very large river, where the tide meets the stream. One example of a supporting detail is that estuaries are known by many different names such as bays, sounds, inlets, harbours, and sloughs. Not all bodies of water with these names are estuaries. They must feature the mixing of fresh and salt water to be a true estuary. Another example of a supporting detail is that estuaries are vital habitats for thousands of marine species. Estuaries have been called the “nurseries of the sea” because the protected environment and the great food provide an ideal location of fish and shellfish to reproduce. Finally, it is clear that the main idea is talking about the estuary and how it works.
