Coral reefs protect coastlines from storms and erosion, provide jobs for local communities, and offer opportunities for recreation. They are also are a source of food and new medicines. Over half a billion people depend on reefs for food, income, and protection.01.02.2019
How does the coral reef system work?
Coral reefs are built by coral polyps as they secrete layers of calcium carbonate beneath their bodies. The corals that build reefs are known as “hard” or “reef-building” corals. Soft corals, such as sea fans and sea whips, do not produce reefs.
What is a reef simple definition?
: a chain of rocks or coral or a ridge of sand at or near the surface of water.
What are the 3 kinds of reef ecosystems?
The three main types of coral reefs are fringing, barrier, and atoll. Schools of colorful pennantfish, pyramid, and milletseed butterflyfish live on an atoll reef in the Northwestern Hawaiian Islands. The most common type of reef is the fringing reef. This type of reef grows seaward directly from the shore.26.02.2021
Where is the world’s largest coral reef system?
Queensland, Australia
Stretching for 1,429 miles over an area of approximately 133,000 square miles , the Great Barrier Reef is the largest coral reef system in the world. The reef is located off the coast of Queensland, Australia, in the Coral Sea.28.04.2022
What is a reef in the ocean?

Why is a coral reef an ecosystem?
Coral reefs provide an important ecosystem for life underwater, protect coastal areas by reducing the power of waves hitting the coast, and provide a crucial source of income for millions of people. Coral reefs teem with diverse life. Thousands of species can be found living on one reef.
What makes a coral reef?
A coral reef is made of thin layers of calcium carbonate
Stony corals (or scleractinians) are the corals primarily responsible for laying the foundations of, and building up, reef structures. Massive reef structures are formed when each individual stony coral organism—or polyp—secretes a skeleton of calcium carbonate.26.02.2021
How reef is formed?
Coral reefs begin to form when free-swimming coral larvae attach to submerged rocks or other hard surfaces along the edges of islands or continents. As the corals grow and expand, reefs take on one of three major characteristic structures — fringing, barrier or atoll.
Where did the word reef come from?
From earlier riff, from Middle English rif, from Old Norse rif (“rib, reef”), from Proto-Germanic *ribją (“rib, reef”), from Proto-Indo-European *h₁rebʰ- (“arch, ceiling, cover”). Dutch rif (“reef”), Low German riff, reff (“reef”), German Riff (“reef, ledge”) are also borrowed from Old Norse.

They base these divisions on location within the reef and characteristics such as depth, wave action, light intensity, temperature, and water chemistry. Zones of the reef include: lagoon, back reef, reef flat, reef crest, and fore reef.
What are the 2 main types of coral?
WHAT ARE CORALS? Despite their ‚rocky‘ appearance, corals are living organisms. There are two main types of corals: (1) hard or reef- building corals, which produce a calcium carbonate skeleton and are at the origin of the ‚reef‘; and (2) soft corals that lack such a calcium carbonate skeleton.

Why the Great Barrier Reef is important?
In Australia, our Great Barrier Reef is an irreplaceable and crucial part of our ecosystem – and our economy. Made up of 3,000 individual reefs, it protects our coastlines and is home to thousands of species of marine life including fish, whales, dolphins and six of the world’s seven species of marine turtle.07.04.2021
What would happen if all the coral reefs died?
If coral reefs disappeared, essential food, shelter and spawning grounds for fish and other marine organisms would cease to exist, and biodiversity would greatly suffer as a consequence. Marine food-webs would be altered, and many economically important species would disappear.28.04.2021
Why is coral reef restoration important?
Coral reefs provide coastal protection for communities, habitat for fish, and millions of dollars in recreation and tourism, among other benefits. But corals are also severely threatened by rapidly worsening environmental conditions. Learn how NOAA works to restore these valuable habitats.27.09.2021

Is the Great Barrier Reef healthy?
Over the 35 years of monitoring by AIMS, the reefs of the GBR have shown an ability to recover after disturbances. In 2021, widespread recovery was underway, largely due to increases in fast growing Acropora corals.
Can we live without coral?
According to the United Nations, around one billion people globally depend on coral reefs for their food and livelihoods. Let that sink in for a second. Their disappearance would be catastrophic; resulting in hundreds of millions of people around the world losing their main source of food and income.01.03.2021
How long until coral reefs are gone?
A 70-90 per cent decrease in live coral on reefs by 2050 may occur without drastic action to limit global warming to 1.5°C. Even with urgent reductions to greenhouse gas emissions, global ocean temperatures could still take decades to stabilize.12.11.2021
