LAGOON

LAGOON

• Sandbars, barrier reefs, coral reefs, and other natural barriers divide lagoons from bigger bodies of water.
• "Lagoon" is derived from the Italian word laguna, which means "pond" or "lake."
• Although lagoons are geographically delimited, the term "lagoon" is occasionally used to refer to a wider territory that encompasses one or more lagoons.
• Laguna Madre on the Texas Gulf Coast, for example, is made up of tiny bays and lagoons, but Laguna Beach in Southern California is a beach and not a lagoon at all.

• Lagoons are classified into two types: atolls and coastal.
• Atoll lagoons arise when an island sinks entirely beneath the ocean, leaving a ring of coral that grows upward.
• A body of water, generally deep, is located in the middle of the ring.
• The interaction of coral growth and water results in a lagoon.
• An atoll's creation might take up to 300,000 years.
• Lagoons occur along gently sloping coastlines.
• They are shallower than atoll lagoons and frequently separated from the ocean by an island, reef, or sand bank.
• Usually, there is an entrance connecting coastal lagoons to the ocean.
• Sea level rise, the amount of existing silt, and the tidal range all have an impact on the formation of coastal lagoons.
• Coastal lagoons, which are younger and more active than atoll lagoons, may have shorter "lifespans" due to their exposed placement on the coastline.
