How was the Great Barrier Reef Made?
- Around 20,000 to 6,000 years ago, the sea level began to raise so do the corals. Scientists suggest that about 13,000 years ago, the sea level was 200 feet lower than it is now.
- According to the Reef Research Center, the land that forms the current reef system thought to be remnants of either volcanoes or older reefs.
- The Australian Institute of Marine Sciences (AIMS) claims that the current Great Barrier Reef had begun during the Last Glacial Maximum.
- The reef started off forming when the free-swimming coral larvae stick to the underwater rocks that occur along the island’s edges.
- As the corals continued to grow, reefs assumed any of the three characteristic structures—barrier, atoll, and fringing. Atolls are circular in shape.
- The corals then attached to the submerged hills to give rise to the present reefs and cays.

Threats to the Great Barrier Reef
- Major threats to the coral reef are climate change, fishing, pollution, and crown-of-thorns starfish.
