  • A lagoon is a shallow body of water that may have an opening to a larger body of water, but is also protected from it by a sandbar or coral reef. 
  • Lagoon is a back water system from sea and no connection with fresh water while estuary is a river mouth region regularly influenced by high tides and low tides of sea. Hence statement 2 is correct. 
  • An estuary is a partially enclosed body of water formed where fresh water from land meets and mixes with salt water from the ocean. Hence statement 1 is not correct. 
  • Estuaries transport and trap nutrients and sediment through the combined action of freshwater flow, wind, waves and tidal action. 
  • A basic feature is the instability of an estuary due to the ebb and flood of the tide. 
  • Estuaries are among the most productive environments on earth. Hence statement 3 is correct. 
  • Formation of estuary: Sea level has slowly risen over the last 15000 years remaining stable over the last 6000 years. As the sea rose it drowned river valleys and filled glacial troughs. Once formed, estuaries make good sediment traps, filling with sediment from both the land and the sea.
