What landform develops on coral reefs as a result of wave action
Talja [164]
A reef is a ridge of a rock of any type of land that extends some distance just under the surface of the water. A coral reef is a lot of calcium carbonate that is also made up of living creatures. A coral reef is created when a small amount of dead coral turns into calcium carbonate. This process is very slow. The famous reefs are the Great barrier Reef of Austria and Belize and Cayman Islands.

The higher areas between the grooves are known as buttresses and may grow together at the top producing arches.
