Tiny corals form the coral reefs. They have different colors. These colors come from the algae (海藻) living inside the coral. Lots of corals stick together. New ones grow on the body of dead corals. This happens year after year. Over time, corals build up a reef. The reef rises from...
There are three type coral reefs. fringing reefs,barrier reefs,and atolls. Fringing reefs sit close to the shoreline at the"fringe"of the land. Barrier reefs have a larger lagoon,or area of water. between the reef and the shore. The largest barrier reef...
Over time, corals build up a reef.The reef rises from the ocean floor until it almost reaches the sea's surface(表面). It takes corals about 500,000 years to build a huge reef. It has taken human beings less than 100years to harm coral reefs.Coral reefs have been harmed in different...
Over time, corals build up a reef. The reef rises from the ocean floor until it almost reaches the sea's surface. 43 While it may take human be-ings a few seconds to harm it.44 People have broken off pieces of coral reefs to sell or keep them. To catch more fish, people have ...

Coral reefs are crucial to the biodiversity of the world's oceans. They cover less than 1% of the ocean floor, but provide food and shelter to over 25% of all ocean creatures—up to 2 million species! Disney scientists and conservationists are working hard in Florida and around the world ...
creatures.Now these beautiful places are in danger.(16)___.Scientists have found that more than one-fourth of the Earth's coral reefs have been ruined so far.Another quarter will disappear in ten years' time.Unless things change,all of the remaining reefs may die within your lifetime.Some...
Coral reefs rely on inter-habitat connectivity to maintain gene flow, biodiversity and ecosystem resilience. Coral reef communities of the Red Sea exhibit remarkable genetic homogeneity across most of the Arabian Peninsula coastline, with a genetic break towards the southern part of the basin. While ...
Given that both climate and the distribution of shallow marine area have substantially varied throughout geological time, the question arises as to the degree to which these factors can explain the observed distribution of fossil coral reefs. Moreover, understanding how these drivers influenced the sp...
