What types of rocks are found there at great barrier reef?

Answer 1

The reef sits on top of thousands of years of compacted coral skeletons that have compressed and fused to form limestone rocks. So yes, there are rocks in the reef as it is principally composed of rock.

Answer 2

It is coral in the Great Barrier Reef, not rocks. But the coral was formed from the rise and fall of the ocean thousands of years ago, during the final years of the Ice Age.

Answer 3

There are some rocks in the coral reefs but mostly living coral organisms. Rocks tend to sit at the bottom of the reefs. But reefs are not made of rocks, but are made of coral. :)

Answer 4

It is made of coral not rock.
