Great Barrier Reef

Great Wall of China is about 4,160 miles Amazon River is about 3,980 miles

The Great Barrier Reef is far bigger than the Grand Canyon. It extends for around 2300 km in length, covers an area of about 300 000 sq km, while the coral reefs (not the ones with living polyps) reaches down to a depth of up to 500m.

The Grand Canyom, by comparison, is around 446 km long and up to 29 km wide, giving it an area of around 12 934 sq km. It is deeper, however, reaching a depth of up to 1.6 km.

The Great Barrier Reef is on the east coast of Australia, within the Coral Sea, which is one of the arms of the Pacific Ocean.

No. The southern end of the Great Barrier Reef begins just northeast of Bundaberg, Queensland, and it is a distance of 1 294 km, or 804 miles from Sydney. The Great Barrier Reef then continues for another 2,300 km up the Queensland coast.

The ideal time to go to the Great Barrier Reef is from late Autumn to late Spring, which is from May to August. During these months, there is less chance of being stung by any of the many marine stingers found in the Great Barrier Reef. The weather is also better, as the days remain warm, but there is not the uncomfortable humidity of summer.

No. The Great Barrier Reef is a marine biome, located in the Coral Sea, which is an arm of the Pacific Ocean. Freshwater runoff from floods is one of the dangers occasionally faced by the Great Barrier Reef.

The Great Barrier Reef itself is an example of mutualism. The corals which create coral reefs such as the Great Barrier Reef have a symbiotic relationship with algae known as zooxanthellae. This algae, which lives within the tissues of the coral, causes a photosynthetic reaction which enables the polyps to make skeletons about three times faster in the light than in the dark. This means the corals deposit skeletons faster than the environment can remove it, and these skeletons build upon each other over time, creating a coral reef.

Many islands lie east of the Great Barrier Reef, as the reef is about 2300 km in length. For example, the islands that make up the countries of Vanuatu, Samoa, Fiji and New Caledonia lie east of the Great Barrier Reef.

Some fish eat coral along with clumsy sharks or whales. The greatest source are humans,who take corals because they look pretty or because the polluting of the sea causes coral to die off.

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.

The Eastern Spiny seahorse - Hippocampus hendriki- lives in the Great Barrier Reef.

The water temperature of the Great Barrier Reef varies between 22 degrees Celsius and 28 degrees Celsius (71 to 82 degrees Fahrenheit), depending on the season and on how far north one travels. As the reef extends for 2300 km down the coast of Queensland, it will tend to be warmer further north.

Winter temperatures do not change dramatically, as the majority of the reef is in tropical and subtropical waters, and coral requires a constant warm temperature range.

Humans have positively impacted the Great Barrier Reef through conservation efforts, such as establishing marine protected areas that safeguard critical habitats and biodiversity. Initiatives aimed at reducing pollution and improving water quality have also contributed to the reef's health. Additionally, research and monitoring programs help to better understand the reef's ecosystem, guiding sustainable tourism practices and fostering community engagement in conservation efforts. These combined actions aim to promote the resilience of the reef against climate change and other threats.

The reef sits on top of thousands of years of compacted coral skeletons that have compressed and fused to form limestone rocks. So yes, there are rocks in the reef as it is principally composed of rock.
