The Great Barrier Reef
By: Abigail Quinn
Location
Title
The Great Barrier Reef is located just off the coast of Queensland, Australia. At some points the reef lies close to shore, while in others it can be as far away from as 150 km (93.2057 miles).
Temperature
Title
In the winter the water temperature ranges up to 24 degrees Celsius ( 75 degrees Fahrenheit) and peaking in the summer, reaching 30 degrees Celsius (86 degrees Fahrenheit).
Fauna
Title
The Great Barrier Reef is one of the world's most complex ecosystems consisting of thousands of animal species. Some of these animals include fish, coral, mollusks, echinoderms, sea-snakes, marine turtles, sponges, whales, dolphins, seabirds, and shorebirds.
Flora
Title
Not many different types of plants grow around the Great Barrier Reef due to the fact that the conditions of an underwater habitat makes it hard for plants to thrive. Though it is hard some different plants grow here. They include different types of algae, sea-grasses, and sea lettuce. One of the most important plants in the Great Barrier Reef is a type of algae called Crustose Coralline. It is important because it helps the coral reef grow by releasing a sediment that acts as a sort of glue to hold the layers of lime stone together.
How They Were Formed
Title
The coral reefs are made up of various layers of limestone. While this is true, there is a process causing it to form and grow. This process is:
- First, a coral larvae will find a rock formation or a similar hard suface to attach itself to.
- Now the coral larvae is a coral polyp and will begin to excrete (poop) a rock substance called calcium carbonate.
- The more calcium carbonate a coral polyp releases the more polyps can attach to that same location and will eventually create the coral reef.
- Finally, the coral polyps die leaving behind their hard exoskeleton so new larvae can attach.
