SSC MTS EXAM

Detailed explanation-1: -A lagoon is a shallow body of water protected from a larger body of water (usually the ocean) by sandbars, barrier islands, or coral reefs. Lagoons are often called estuaries, sounds, bays, or even lakes.

Detailed explanation-2: -The main difference between lagoons and estuaries is in the flow dynamics of the water bodies: in estuaries, the water flows fast and strong, while in lagoons the water is more shallow and flows sluggishly. Estuaries are usually deeper than lagoons (Kjerfve, 1986).

Detailed explanation-3: -The combination of coral growth and water creates a lagoon. It may take as long as 300, 000 years for an atoll formation to occur. Coastal lagoons form along gently sloping coasts. They are generally shallower than atoll lagoons and tend to be separated from the ocean by an island, reef, or sand bank.
