Island formed by a volcano peak emerging from the ocean. Ring shaped coral reef
|
Detailed explanation-1: -This circular type of coral reef, called an atoll, is created as a ring of coral surrounds an undersea volcano that has risen above the water’s surface. Long after the volcano has receded into the ocean, the atoll remains. The habitat inside the atoll, protected from the open sea by the sturdy reef, is called a lagoon.
Detailed explanation-2: -Anyhow, Lakshadweep is the one and only coral island chain present in India. These islands had been formed by the accumulation of coral on the volcanic tops of the Indian Ocean ridge that sank below the surface around millions of years ago presumably because of a rise in sea levels.
Detailed explanation-3: -The word atoll comes from the Dhivehi word atholhu (Dhivehi: , [ˈat̪oɭu]), Dhivehi is an Indo-Aryan language spoken in Maldives. The word’s first recorded English use was in 1625 as atollon. Charles Darwin coined the term in his monograph, The Structure and Distribution of Coral Reefs.
Detailed explanation-4: -The definition of an atoll is a ring shaped coral reef, or close coral islands that enclose or almost enclose a lagoon. The Bikini in the Pacific Ocean is an example of an atoll.
