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.

Wave actions are usually not a problem due to hard coral reefs. The reef reduces a wave energy. But sometimes waves can break off or flatten large portions of coral reefs, forming grooves in once circular reef. The higher areas between the grooves are known as buttresses and may grow together at the top producing arches.
Answer: Landform that develops on coral reefs as a result of wave action are Arches.
