The Largest coral reef in the world is found near the coast of which one of the following countries?
- (a) Australia
- (b) Cuba
- (c) Ghana
- (d) Philippines
Show the answer and explanation
Answer: (a) Australia
The Great Barrier Reef off Queensland, Australia, is the largest reef system in the world (~2,300 km).
Why the others are wrong
(b) Cuba has large reefs, but not the largest.
(c) Ghana’s Atlantic coast has almost no reefs — cold, muddy water.
(d) The Philippines is in the Coral Triangle (richest diversity), not the largest single reef.
The trap
Richest reef region (Coral Triangle) is not the largest reef.
🔒 Largest reef: Great Barrier Reef (Australia). Second: Mesoamerican Barrier Reef (Belize).
