Answer 1

The correct answer is B. An atoll is a coral island formed on top of a volcano, and a lagoon is the water enclosed within it.

Step-by-step explanation:

An atoll is the result of geological processes in which a volcanic island is submerged in the sea forming a lagoon with an exit to the sea in its crater, also this is characterized by the formation of corals around it. On the other hand, a lagoon is a container of freshwater that is usually found in continental areas or in atoll. So, the correct answer is B. An atoll is a coral island formed on top of a volcano, and a lagoon is the water enclosed within it.
