How was it formed?
The Great Barrier Reef, it has a length of 1,600 miles (2,600 km) and covers 133,000 square miles (344,400 sq. km). The Great Barrier Reef is the largest structure in the world created by living organisms. It supports a wide diversity of life, this includes fish, whales, dolphins, sea turtles and many more. This is the same reason why reef corals exist, also known as the “rainforest of the ocean”.
What types of rock are found there
There are not types of rocks found in the reef. Most rocks that are found in the reef would be limestone. The rocks found there were mainly limestone because of the life and death of animal organism and plants.
How the rocks where formed
The Great Barrier Reef was formed many years ago. The reef is built on foundations layers of dead coral that was made out of the skeletal and coral fragments and marine forming a wall made out of limestone. Plants, animals and organisms such as oysters, clams, mussels and coral use calcium carbonate (CaCO3) which is found in seawater to create their shells and bones. As these organisms die, their shells and bones are broken down by waves and settle on the ocean floor where they are compacted over millions of years, creating limestone from the sediments and the pressure

The reefs on Australia’s continent have taken different form depending on the sea level and the current formation is about 6,000 to 8,000 years old. According to marine science the Great Barrier Reef began to form during the last glacial maximum. This occurred 26,500 to 20,000 years ago. About 13,000 years ago the sea level was 60.95 meters lower than the current level. Soon then the coral started growing around the coastal plain which had become continental islands. The sea level began to rise during a warming period as the glaciers melted. Most of the continental island started to join, and the coral started to form the reef and cays of
The Barrier Reef is the largest reef in the world, and it is located in Australia. It is made up of different types of coral and fish, but sadly the reef is bleaching. Bleaching is the process of water temperatures getting too warm and as a result coral reefs can bleach. When water gets too warm, corals will get rid of the algae living inside their tissues causing the coral to turn completely white. Although, when coral reefs turn white this does not mean that they are dead, coral reefs can actually survive a bleaching event. It just means that the coral is under a lot of stress and
Although scientists are not able to depict exactly when humans first came into contact with the reef, evidential estimations state that the Great Barrier Reef was first formed approximately 500,000 years ago, with the current reef state being formed about 6,000 to 8,000 years old.
To summarize Rowan Jacobsen’s article in Outside magazine, Obituary: Great Barrier Reef (25 Million BC-2016), it is titled the complete death and passing of the Great Barrier Reef in Australia. Jacobsen says the famous Barrier Reef passed away in 2016 at 25 million years old. He says the Barrier Reef is the largest living structure; stretching 1,400 miles long, 2,900 individual reefs, and 1,050 islands. This grand reef harbors thousands of species. The
The Great Barrier Reef is one of the most beloved regions of the world but due to recent human activity in surrounding areas and subsequent sediment delivery, coral and seagrass habits within are being negatively impacted. Extending 2000km along the North-eastern Australian coast (Brodie et al., 2007), the Great Barrier Reef is a major source of income for Northern Australia and fuels the growth of local businesses. As industrialization in areas adjacent to the Great Barrier Reef lagoon have increased since European settlement (McCulloch et al., 2003), the need for more resources to compensate for human population has led to harmful land practices such as overstocking and deforestation for cattle grazing inland. These are causing a significant
Biophysical interactions refer to the ways in which the four spheres, atmosphere, lithosphere, hydrosphere and biosphere interact with each other, which in turn leads to their diverse ecosystem functioning and the extent and nature to which they operate. The Great Barrier Reef is a diverse underwater marine ecosystem located off the coast of northern Queensland, it stretches 2300km to Fraser Island, has 3 000 different reefs and it is considered the largest living structure on the planet. The biophysical interactions including the dynamics of weather and climate, geomorphic and hydrological process biogeographical processes and the adjustments in response to natural stress all lead to the diversity and functioning of the Great Barrier Reef
Introduction Stretching a massive 3,000 km along Queensland’s coastline, beginning at the top of the Cape York Peninsula in the north, extending down to Bundaberg in the south and covering 348,000km2 is where lays the Great Barrier Reef.
The Great Barrier Reef is the world’s largest coral reef system. It is located in Queensland and stretches 2,300 km along the coast, covering 348,000 km2. The Great Barrier Reef Marine Park Authority was established in 1975 in order to sustainably manage the natural heritage for future generations.
The Great Barrier Reef is an oceanic/costal ecosystem off the coastline of Port Douglas, Australia. There are man costal systems that are significant to the role of the Reef including coral reefs, wetlands, and rainforests etc. The reef consists of many diverse corals and is a home for over 1,500 different species of fish. The reef is unique for many distinctive reasons; a reason that is unique is that it is acknowledged as one of the most imperative biological possessions. The Reef is a complex ecosystem with numerous organisms trusting on each other for nourishment and endurance. Broadly all collections of maritime plants and animals are extravagantly signified in the Reef. The animals range from dugongs
The Great Barrier Reef is a huge, complex ecosystem located off the east coast of northern Queensland and is considered as an ecosystem at risk. It stretches approximately 2300km from Papua New Guinea’s Fly River in the north (8⁰S) to Fraser Island in the south (24⁰S) and has become the largest World Heritage site in the world. It has 1500 of the worlds 13 000 fish species in it area, 200 bird species, 5oo species of seaweed, 600 species of echinoderm, 125 species of shark and ray and around 360 species of hard coral.
Barrier reefs are defined as, a coral reef running parallel to the shore but separated from it by a channel of deep water ("About The Reef“). These reefs are all over the world and are some of the most beautiful sites to see. In fact, one of the seven wonders of the natural world is a barrier reef. The Great Barrier Reef is in Australia off the Queensland coast ("About The Reef“). The reef stretches around 1,800 miles down the Queensland coast, and can get to 40 miles wide ("About The Reef“). The Great Barrier Reef is home to many animals including: 1,500 species of fish, 200 types of birds, and 20 different types of reptiles ("About The Reef “). The amount of life that lives in these waters just add to the amazement of the Great Barrier Reef. Many people go to this reef for many different reasons. People go to see the amazing coral reefs, humpback whale breeding, and many endangered species ("About The Reef”). Although there are so many beautiful aspects of the Great Barrier Reef, there are many things that make it a Not-so Great Barrier Reef.
Coral reefs around the world are in danger. One of the causes is global warming, which has been increasing the temperature of the ocean water resulting in coral bleaching. This essay will focus on damage occurring to the Great Barrier Reef.
The sheer enormity of the Great Barrier Reef, in addition to its great age, are two of the most well-known features of this natural phenomenon. It is composed of living coral, dead coral, algae, sponges, fish, snakes and thousands of other species, both plants and animals (2011). Currently, no evidence has been discovered as to when the first human contact occurred at the reef, but the Aboriginal population may have been the first, due to their occupation of Australia for over 40,000 years (Lunar).
The Great Barrier Reef is a reef located in the Coral Sea, on Australia’s north-eastern coast. It stretches more than 2,300km along the state of Queensland’s coastline, beginning at the tip of Cape York Peninsula in the north and extending down to Bundaberg in the south.
Corals build colonies that secrete calcium carbonate to form ocean reefs. When they're healthy, coral reefs provide shelter and food for animals all along the food chain, including the top: us. Across the planet, half a billion people rely, directly and indirectly, on corals for their living. That's why what happens to the 9,000-year-old Great Barrier Reef, as well as to other reefs worldwide, is critical. The floods in Queensland have hurt the Great Barrier Reef by funnelling into the ocean vast plumes of freshwater and agricultural runoff that could severely damage the coral. Besides the extreme rain that sparked the floods, rising ocean temperatures, changes to the ocean's chemistry and the global trade in natural resources — all symptoms of our fossil-fuel economy — are waging a multiform war on the marine
Coral reefs are one of the oldest types of living systems on earth, and certainly one of the most spectacular (Goreau, 1987). They are massive underwater structures formed by the limestone skeletons of tiny invertebrate animals. Reefs house a greater diversity of body forms, chemistry, and animal phyla (thirty-two compared to the eight that inhabit the most biodiversity ecosystems on land). Phyla comprise the second largest category of living things, after kingdoms.
