As an island sinks, the fringing reef gradually becomes a barrier reef. If the island continues to sink, the barrier reef eventually becomes a signature atoll.

A reef that surrounds a volcanic island is what?

A reef that surrounds a volcanic island is known as a fringing reef. These reefs usually form close to the shoreline and develop on the shallow-water platform around the island. The growth of corals on the fringing reef is influenced by the volcanic activity and the geography of the island.


How can an island with fringing reefs become atoll?

An island with fringing reefs can become an atoll through a process known as subsidence. As the volcanic island gradually sinks due to tectonic activity or erosion, the surrounding coral reefs continue to grow upward toward the sunlight. Over time, the island may completely submerge, leaving a lagoon surrounded by the coral reef, thus transforming the fringing reef into an atoll. This process can take thousands to millions of years.


Was Bora-Bora formed by a volcano?

Bora Bora exemplifies what Charles Darwin called an "almost atoll," a barrier reef island formed by an oceanic volcano with a fringing coral reef. Over the course of the years, as the surrounding coral reef grows upward, the island with the volcano sinks.

How is a barrier reef alike to a frining reef?

A fringing reef grows in shallow waters usually a few feet from shore or in lagoons. They are often confused for barrier reefs just by the overall growth of the reef. However, with barrier reefs there is usually a deep portion and located farther from shore than with a fringing reef.
