At this point, the reef is called a fringing reef. It surrounds the island just below the surface of the water. They include sub-oceanic volcanism; limestone covered blocks created by the destruction of an active volcano in a cataclysmic eruption; and tidal movements. The lack of any exposed or associated volcanic rocks in the Chocolate Hills refutes the popular theories involving volcanic eruptions. The theories involving either a sudden, massive ...Limestone areas are predominantly affected by chemical weathering when rainwater, which contains a weak carbonic acid, reacts with limestone.

Another type of chemical weathering works on rocks that contain iron. These rocks turn to rust in a process called oxidation. Rust is a compound created by the interaction of oxygen and irontunnels and underground excavations, horizontal underground passageway produced by excavation or occasionally by nature’s action in dissolving a soluble rock, such as limestone.
