circular coral reef 5 letters?
They are structures made up of organisms found in shallow waters in the tropics with little or no food. Excessive food in water in areas such as the estuaries of irrigation drains in agricultural areas harms coral reefs as a result of the formation of algae on them.
It is highly concentrated in tropical and tropical waters in the Indian and Pacific Oceans, the Red Sea, the Arabian Gulf, around the Gulf of Mexico and the West Indies, and it breeds in shallow waters with depths not exceeding 50 m, where there are clear waters, adequate lighting, moderate water salinity, and little change in temperature. . It is noted that the largest and greatest coral areas in the world are concentrated off the coast of Australia, where the Great Barrier Reef is, as well as off the coast of the Maldives, and off the coast of eastern Africa and the coasts of the Arabian Sea, the Red Sea and the Arabian Gulf.

How large is the coral area?
The area of coral in the world is 660,000 km², equivalent to 0.2% of the area of oceans and seas. Coral reefs grow very slowly, at a rate ranging between 0.2-0.7 cm per year, and coral growth continues for hundreds of years.
Most of the coral reefs formed after the last ice age when melting ice caused sea level to rise and flooded continental shelves. Most of the coral reefs are less than 10,000 years old. With the establishment of local communities, coral reefs grew upwards, resulting in rising sea levels. Corals that have risen too slowly can sink without adequate lighting. Coral reefs are found in the deep sea far from the continental shelves, around oceanic islands and atolls. Most of these islands are volcanic in origin. Others have tectonic origins where plate movements raise the deep ocean floor.
