Where do atoll Reefs grow?
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.

An island of coral that encircles a lagoon partly or completely.
Coral Reefs need carbon dioxide and sunlight to grow. As well as the ocean water, of course!
In most cases, the land area of an atoll is very small in comparison to the total area. Lifou (land area 1146 km²) is the largest raised coral atoll of the world. Lif…ou is a commune in the Loyalty Islands Province of New Caledonia, an overseas territory of France in the Pacific Ocean. It is situataed about 190 klms east of the New Caledonian mainland. It is the largest of the Loyalty Islands and is also the most heavily populated.

The formation of a coral reef begins when stony coral larvae, known as polyps, attach themselves to hard surfaces such as submerged rocks along island or continental edg…es. These polyps reproduce and become a colony, which features a base attached to the hard surface, an edge zone where new coral polyps are produced, and an upper surface that is exposed to light.
It grows 1 inch per 100 years. (serious answer)
They grow as much as 4.5 cm year. But colonies of coral grow as much as 10 cm a year
Most coral reefs are in the more shallow water. Though there are some in the deep water also. It depends on the types of corals being grown how deep they will grow.
It will take millons and millons of years Wrong! Depending of the coral, starting from 1cm/year up to 50cm/year in species like xenia
Features of an atoll are: They thrive in warm tropical and subtropical waters. Most are found in the Pacific Ocean. They are products of the growth of topical sea organi…sms. They are usually round and formed around a lagoon.
Yes, it is possible, you need a salt water tank and let it sit and make sure it is in sunlight. Check out more information about coral reefs at destructionofcoralreefs.weebly.…com
Atolls develop in the remnants of volcanic islands. As the island ages and erodes, it becomes an atoll with the crater at the center.
The agitation clears away sediment, which can block the light that is required for the photosynethic algae to grow on coral reefs. The removal of sedimentation also enables th…em to properly respirate, otherwise the tiny coral polyps could suffocate. The water where coral reef's flourish also lack many nutrients, which is why it is clear. The waves (agitation) help deliver nutrients to animals, like sponges, that have a symbiotic relationship with the coral reef.
How can coral atoll be attached to ocean floor when coral cannot live or form reefs in the 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 ol…d. 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.
The geological record indicates that the ancestors of modern coral reef ecosystems were formed at least 350 million years ago. The coral reefs existing today began growing as …early as 50 million years ago. Most established coral reefs are between 5,000 and 10,000 years old. Although size can be a good indicator of the age of a coral reef, it is not a certain indicator. Different species of coral grow at different rates, depending on the water temperature, oxygen level, amount of turbulence, and availability of food around them. Most massive boulder corals are the slowest growing species, adding only between 1/4 to 7/8 inch (5 to 25 millimeters) per year to their length. Branching and Staghorn corals may grow much faster, adding as much as 8 inches (20 centimeters) to their branches each year.
Is it true that a problem encountered in the island-hopping campaign in the central pacific was that many of the islands were coral reef atolls?
Coral reefs are underwater structures made from calcium carbonate secreted by corals. Coral reefs are colonies of tiny animals found in marine waters that contain few nutrient…s. Most coral reefs are built from stony corals, which in turn consist of polyps that cluster in groups. The polyps belong to a group of animals known as Cnidaria, which also includes sea anemones and jellyfish. Unlike sea anemones, coral polyps secrete hard carbonate exoskeletons which support and protect their bodies. Reefs grow best in warm, shallow, clear, sunny and agitated waters.
