Why do corals turn white?
Warmer water temperatures can result in coral bleaching. When water is too warm, corals will expel the algae (zooxanthellae) living in their tissues causing the coral to turn completely white. This is called coral bleaching.
Is the Great Barrier Reef the biggest reef in the world?
The Great Barrier Reef is the world’s largest coral reef system composed of over 2,900 individual reefs and 900 islands stretching for over 2,300 kilometres (1,400 mi) over an area of approximately 344,400 square kilometres (133,000 sq mi). The reef is located in the Coral Sea, off the coast of Queensland, Australia.
What caused the Great Barrier Reef to die?
Coral reefs are dying around the world. Damaging activities include coral mining, pollution (organic and non-organic), overfishing, blast fishing, the digging of canals and access into islands and bays. Other dangers include disease, destructive fishing practices and warming oceans.
What will happen when coral reefs die?
Once the coral is dead, the reefs will also die and erode, destroying important marine life spawning and feeding grounds. And these are just the results that scientists can predict with near certainty — though many point out they can’t predict everything that might happen if the coral reefs disappear.
What is the best time of the year to visit the Great Barrier Reef?
Best Times to Visit Great Barrier Reef. The best time to visit the Great Barrier Reef is from June to October. This peak season offers some key advantages for travelers. Temperatures hover in the low 60s to mid-80s, and rainfall is uncommon, which means clearer waters and better diving conditions.
Where would a coral reef most likely be found?
Corals are found all over the world’s oceans, from the Aleutian Islands off the coast of Alaska to the warm tropical waters of the Caribbean Sea. The biggest coral reefs are found in the clear, shallow waters of the tropics and subtropics.
How fast can coral grow?
The massive corals are the slowest growing species, adding between 5 and 25 millimeters (0.2–1 inch) per year to their length. Branching and staghorn corals can grow much faster, adding as much as 20 centimeters (8 inches) to their branches each year. Coral reefs grow best in warm water (70–85° F or 21–29° C).
What conditions are needed for coral reefs to survive?
Clear water: Corals need clear water that lets sunlight through; they don’t thrive well when the water is opaque. Sediment and plankton can cloud water, which decreases the amount of sunlight that reaches the zooxanthellae. Warm water temperature: Reef-building corals require warm water conditions to survive.

How bad is coral bleaching in the Great Barrier Reef?
The algae provides up to 90% of the coral’s energy. Bleached corals continue to live but begin to starve after bleaching. In 2016, bleaching of coral on the Great Barrier Reef killed between 29 and 50 percent of the reef’s coral. In 2017, the bleaching extended into the central region of the reef.
