What type of landscape is the great barrier reef

The Great Barrier Reef is one of the world's biggest natural wonder and the largest complex coral reef system on the entire planet. It's made up of almost 3,000 individual reefs that sprawl out over an area of 344,400 square kilometres, including 900 paradise islands in its clutches.

Coral reefs are important marine landforms that have existed for hundreds of millions of years. They are composed of the dead skeletons of calcium carbonate (CaCO3 C a C O 3 ) based organisms. These are organisms with hard exoskeletons, and their skeletons provide a foundation for the next generation of organisms.
