i think personally that they form in the ocean from 13-18 celcious
They occur natually; there is no reason behind them.
The tropical oceans near the equator is home to the majority of coral reefs. The largest coral reef is the Great Reef in Australia.
Lion fish live in coral reefs. Most coral reefs occur between 100 and 300 feet deep water.
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.
The three types of reefs are fringing reefs, barrier reefs, and atolls. Fringing reefs grow close to the shorelines of islands or continents, barrier reefs are separated by a lagoon from the land, and atolls are circular coral reefs surrounding a central lagoon, often found in the open ocean.
reefs
The plural of 'reef' is reefs.
Because the animals that build most of the reef require strong illumination from the sun, and that is only available near the surface.
I don't believe tornadoes occur over water. Maybe a better question would be "How do hurricanes effect Coral Reefs".
no dolphins are not in coral reefs.
lots of humans touching the reefs
