fringing veins
Above where the earth's plates meet.
Atoll reefs form lagoons.
It could have been an underground volcano and then a rift formed and it erupted and rose above sea level.
The plural of 'reef' is reefs.
Coral reefs can take four forms; fringing reef, platform reefs, barrier reefs and atolls. Fringing reefs are narrow and shallow, and generally occur near the shore, they literally are a thin 'fringe' along the coast. Platform reefs are reef outcroppings far from shore that occur in calm water. They often have a shallow lagoon, and are flat on top. Barrier reefs are reefs growing along a coastline that are separated from the coastline by a lagoon. Barrier reefs are very similar to fringings except that they are much larger. Atolls are ring reefs that usually form at the base of a volcano. Over time the volcano dissapears, leaving a rin of reef surrounded by deep ocean.
Coral atoll are tiny sea animals that live in shallow water, but when reefs form the new coral grow over the skeleton of the old. As the ocean crust beneath the volcano sinks, the coral sinks with it, and the new coral continues to form on top of the old. Eventually, coral covers the whole volcano. It can survive with the ocean waves bringing in new food and more marine life.
No. Pumice forms above ground as frothy molten rock erupts from a volcano.
How did the volcano kohala form
Atoll reefs usually only form where stony coral growth is quite rapid. They are far more common in pacific reefs than atlantic. However, an atoll is simply a coral reef that encloses a lagoon, and technically they could form anywhere where reefs form.
Islands can form through volcanic activity, where lava builds up from underwater volcanoes and eventually rises above the surface. They can also form through processes like coral reefs growing on submerged land or through the movement of tectonic plates causing land to rise above sea level.
WHat is a volcano
Mountains form when the volcano reaches the surface
