The depth of the Great Barrier Reef varies. The coral which makes up the Great Barrier reef is believed to extend to a depth of around 500m in some places, but the actual living polyps only go down as far as 30 metres. The water in the channel between the shoreline and the reef reaches about 60 metres in depth.
There are no continents immediately east of the Great Barrier Reef. The closest continent east of the reef is South America, and it is many thousands of kilometres away. The continent of Australia, however, lies directly west of the Great Barrier Reef.
In places it is. The coral which makes up the Great Barrier reef is believed to extend to a depth of around 500m (1640 feet) in some parts of the Reef. However, the living polyps themselves only go down as far as 30 metres (almost 100 feet). The water in the channel between the shoreline and the reef reaches about 60 metres (197 ft) in depth.
This is the Great Barrier Reef. Running to a length of about 2,300 kilometres, and roughly parallel to the Queensland coast, it is the largest coral reef in Australia and, indeed, in the world.
There is no string of purely coral islands in this location. The Great Barrier Reef forms a 2300 km long string of coral reefs, islands and atolls running roughly parallel to the northeast Australian coast.
The Mesoamerican Barrier Reef System stretches from the tip of the Yucatán Peninsula down to the Bay Islands of Honduras. It includes the Belize Barrier Reef. This reef structure is the largest coral reef in the Western Hemisphere and the second largest barrier reef in the world.
This is the Great Barrier Reef, the world's largest coral reef and the only living organism visible from space. It extends about 2300km down the coast of Queensland.
The Great Dividing Range (also called the Eastern Highlands) is the mountain range which runs down the complete length of eastern Australia. The Great Barrier reef runs the length of 2300 km parallel to the coast of Queensland. There are many mountains along this range which are close to the reef.
Figures vary, but according to the Australian Institute of Marine Science, the Great Barrier Reef is approximately 2,300km long. It is located in the Coral Sea and lies parallel to the coast of Queensland. It is actually a series of reefs and atolls, with its northern end just south of Papua New Guinea, and its southern end near Lady Elliott Island, northeast of the city of Bundaberg. This is the equivalent of about 1,430 miles.Australia has almost one-fifth of the world's reef area and most is located in the Great Barrier Reef, off the eastern coast. The Great Barrier Reef World Heritage Area, which comprises more than just the coral reefs, atolls and islands of the Great Barrier Reef, covers around 348,000 sq km (134,363 sq miles) while the Great Barrier Reef Marine Park itself covers around 344,400 sq km.
If you are pinning it down to only two, they would have to be Ayers Rock and the Great Barrier Reef.
Yes; most of the reef is very shallow, so free diving it is quite common.
The Great Barrier Reef is the largest coral reef in the world. It extends 2300 km down the coast of Queensland, Australia. However, it is not the only coral reef in Australia. On the west coast, off Exmouth, is Ningaloo Reef, another impressive coral reef.
