Microsoft Rewards Bing Homepage Quiz: What is the world’s largest coral reef?
A Florida Reef
B Great Chagos Bank
C Great Barrier Reef
The Great Barrier Reef off Australia is the largest reef system in the world, made up of 2,900 individual reefs and 900 islands that extend 1,400 miles, longer than the state of California. Covering an area of 133,000 square miles, it’s considered the largest single structure made by living organisms and can be seen from space.
The reef is separated from the Australian mainland by a channel up to 100 miles wide so it’s not easily accessible. Although it’s protected as a marine conservation area, the reef is not immune from the harmful effects of coral bleaching. Massive die-offs have been confirmed, as have new species of coral, suggesting the reef is undergoing a period of natural selection.
The correct answer is Great Barrier Reef.
