Less than 1%. I hope that wasn't a question in your homework. The previous answer was ridiculously wrong!
I did the math, and they cover nearly 7%. Check it for yourself - the surface area of the world is 510 million square kilometres, and the surface area of the oceans is 361 million square kilometres. Coral reefs cover nearly 10% of the ocean's total area. 36.1 million over 510 million x 100 gives you just over 7%, but the real figure is slightly less because coral reefs account for NEARLY 10% of the ocean's surface area. Even if it was 9.5% of the ocean's area, coral reefs still cover over 6.7% of the world's total surface area. Hope this helps!
What else can I help you with?
What might happen to coral if a lot of nutrients were introduced into the water?
Excessive nutrients in the water can lead to algal overgrowth, which can smother coral and disrupt their ability to photosynthesize. This can weaken the coral and make them more susceptible to disease. Additionally, increased nutrient levels can also lead to ocean acidification, further stressing the coral.
What is the meaning of coral reef formation?
Coral Reefs - are stony structures formed underwater . They are mostly madeup of the framework of dead corals . They come in different sizes , shapes , and colors making them look like a beautiful sea garden .Coral - are large colonies of small animals called POLYPS . These polyps reside within a cup-like calcium carbonate skeleton .
How much does a coral reef grow in 100 years?
The growth rate of a coral reef can vary greatly depending on different factors such as water temperature, nutrient availability, and wave action. On average, coral reefs can grow between 1 to 3 centimeters per year. Therefore, in 100 years, a coral reef might grow between 1 to 3 meters in total.
How much precipitation does the coral reef receive in a year?
The amount of precipitation received by a coral reef can vary depending on its location, but on average, coral reefs receive around 1,500-2,000 millimeters of rainfall per year. This precipitation is crucial for providing the necessary nutrients and freshwater to support the diverse marine life within the reef ecosystem. Additionally, the timing and distribution of rainfall play a significant role in the health and resilience of coral reefs in response to environmental stressors.
Why are corals unique?
Because onnce a guy was scuba diving and noticed coral reefs were dying to he took the coral reef to a aquarium and broke pieces of them and hung them by astring in the water and repeated the process so that's why there's so much of them
How much wind is the in coral reefs?
there is not wind considering coral reefs is underwater
How much of the marine environment do coral reefs make up?
Coral reefs cover approximately 0.1% of the world's ocean surface. Despite their relatively small area, they are incredibly biodiverse and provide critical habitats for a wide range of marine species. Coral reefs are often referred to as the "rainforests of the sea" due to their rich ecosystems and the essential services they provide, such as coastal protection and supporting fisheries.
How much of the marine environment do coral reefs makeup?
Coral reefs make up less than 1% (around .7% estimated). However, as years pass, that number is decreasing due to global climate change.
How much rain does coral reefs receive?
none
How much of the earths is considered marine?
Marine regions cover about three-fourths of the Earth's surface and include oceans, coral reefs, and estuaries
How much coral worth?
i would say that coral is dieing a little piece would be about $15.00 (coral reefs) :)
Are coral reefs threatened?
we have too much CO2 in our atmospherein the future or present, the CO2 is absorbed by the oceanmaking it more acidic killing the coral reefs
How much of the Earths surface is considered marine?
Marine regions cover about three-fourths of the Earth's surface and include oceans, coral reefs, and estuaries
How much pressure do coral reefs have?
15,000 tons of pounds
Where is it impossible for coral reefs to grow?
Most of the reef building corals and animals on a reef are dependant on high amounts of sunlight; thus coral reefs are restricted to the tropics where sunlight is abundant. There are deep water sponge reefs in temperate and artic regions, but they are much different from coral reefs.
Where are all the places in the world that coral is found?
Under water. Seriously, most any coast in the equatorial region will have coral reefs, or at least areas of coral growth. Some coral is capable of surviving in colder waters, so some coasts further away from the equator also have reefs, but no where near as much.
Are the Bahamas coral or volcanic islands?
No. The Bahama are made of limestone, with much of the material coming from old coral reefs.
