How much of the earth is ocean

1. 18 million SE) are marine. Covering more than 30 percent of the Earth’s surface, the Pacific Ocean is the largest water mass on But recent research suggests that the Earth’s natural climate variability—natural, short-term fluctuations in the climate system that occur on a year-to-year basis or longer—may have played the most pivotal role of all by transferring excess heat from the Earth’s surface into the deep ocean. With so much of the Earth’s surface taken up by ocean, it’s evident how vital these marine environments are to the planet, and how much there still is to be explored. It's hard to imagine, but about 97 percent of the Earth's water can be found in our oceans. The Earth is often compared to a majestic blue marble, especially by those privileged few who have gazed upon it from orbit. Signatures of Anthropogenic climate change will not impose much extra variation on this pattern. This is clearly not true for the element sodium, so the ocean's missing salt refutes belief in an old earth. And there is life So much more than you might think. How much plastic is there in the ocean? By David Shultz Dec. The full-disk visible satellite view of Planet Earth in Figure 1 shows all the major subsystems of the Earth system. Water cooling for the Earth's crust: Seawater penetrates much deeper than previously thought. There are five oceans: the Antarctic, Arctic, Atlantic, Indian, and Pacific Oceans. Enjoy a range of interesting facts about the Pacific, Atlantic, Indian, Arctic and Southern Oceans as well as information relating to marine life, historical events and How much water is in the atmosphere? Water is an exceptionally interesting chemical with many important implications for life on Earth and the circulation of the atmosphere. While both the Moon and the Sun influence the ocean tides, the Moon plays the biggest role because it is so much closer to our planet than the Sun. Scientists believe we've only barely begun to learn about what lives in the deep ocean Additionally there are two large ice sheets floating in seas off Antarctica, plus floating pack ice in the Arctic Ocean and surrounding Antarctica. This is a remarkable statistic when you consider that reefs cover just a tiny fraction (less than one percent) of the earth’s surface and less than two percent of the ocean bottom. Retrieved I keep being presented with 'earth curvature experiment' videos recently, by flat/concave earth advocates. The Atlantic Ocean is east of the Americas and west of Europe and Africa. The Pacific Ocean measures over sixty-four million square miles, and covers thirty-five percent of the planet with ocean water. It’s in the ground, forms big oceans, and it’s in our atmosphere. Like a hot water bottle on a cold night, the heated ocean will continue warming the lower atmosphere well after greenhouse gases have stopped increasing. Fresh water exists in liquid form in lakes and rivers and as water vapor in the atmosphere, which causes much of Earth's weather. Candace Major is a program director in NSF’s Division of Ocean Sciences. 2 million (±0. EVANSTON, Ill. The twice-daily ocean tides are primarily the result of the Moon’s differential force on the material of Earth’s crust and ocean. That’s the conclusion from experiments on rocks typical of those in the mantle transition zone, a global buffer layer 410 to In your everyday life you are not involved much with saline water. 1,2 If not for the large heat-storage capacity provided by the oceans, the atmosphere would warm more rapidly. Such an ocean might contain more liquid water than all the Earth's oceans combined! The Great Barrier Reef off the eastern coast of Australia can be seen from the moon! Picture yourself on a beautiful beach, anywhere in the world. These images attempt to show three dimensions, so each sphere represents "volume. 97% of all the water on Earth, and 99% of the habitable space on this planet, is in the ocean. There are five major ocean basins. There's a whole lot of water on Earth! Something like 326,000,000,000,000,000,000 gallons (326 million trillion gallons) of the stuff (roughly 1,260,000,000,000,000,000,000 liters) can be found on our planet. The ocean is one of these places. Almost seventy-one percent of the Earth is covered by ocean. Most sea animals extract oxygen directly from ocean water, while land animals breathe air from Earth’s atmosphere, which consists of about 21 percent pure oxygen. It has a solid and active surface with mountains, valleys, canyons, plains and so much more. 3 million SE) species globally, of which ∼2. 2% (148,940,000 sq km) There are a total of 5 oceans, and they are the Arctic, Pacific, Atlantic, Indian, and the Antarctic Ocean. The ocean is the #1 source of protein for more than a billion people. Much of this deep ocean water is between 0-3 degrees Celsius (32-37. That’s more than all of the world’s rainforests combined. org, ). Scientists have used these measurements to derive the amount of chlorophyll, and by extension, phytoplankton, in a given ocean region. Second, global warming causes glaciers and ice sheets to melt, which adds more water to the world's ocean, again causing sea level to rise 4,5. Green algae are not as common in the ocean as brown and red seaweed. It is not distributed equally with respect to the Equator. On Earth We're Briefly Gorgeous is a letter from a son to a mother who cannot read. Of the tiny percentage that's not in the ocean, about two percent is frozen up in glaciers and ice caps. com/ MY TWITTER: http://www. While the Earth’s oceans are known as five separate entities, there is really only one ocean. Panthalassa The original global ocean. As difficult as it may be to believe, the Pacific Ocean is larger than the landmass of every single continent and island combined. How the Last Ocean on Earth Will Die. 62 x (10 to the power of 8) km²). 40 x (10 to the power of 8) miles². There are five ocean biomes - Atlantic Ocean, Pacific Ocean, Indian Ocean, Southern Ocean, and the Arctic Ocean. OCEAN GEOGRAPHY. Europa’s vast and unfathomably deep ocean is widely considered the most promising place to look for life beyond Earth. Water ice and perhaps liquid water occur beneath the frozen surfaces of three of Jupiter's moons, although currently none have free surface waters. Geological evidence indicates very clearly that at times in the Earth's past icecaps were much larger in extent--and alternately, at other times icecaps were virtually nonexistent. Why does the CO 2 concentration change so much? This is a big question whose answer involves many factors, but consider two that are relevant to what we'll learn about in this module. Currently, there are many NASA missions that are simultaneously measuring a myriad of Earth's water cycle variables; Evaporation, Condensation, Precipitation, Groundwater Flow, Ice Accumulation and Runoff. " They show that in comparison to the volume of the globe, the amount of water on the planet is very small. Take a deep breath, gang, as we dive into our ocean facts! Top ten ocean facts. Our ocean covers 72% of the earth’s surface. If Earth was the size of a basketball, all of its water would fit into a ping pong ball. 30% of life on earth is on the ocean floor. An example of a temperature anomaly is how much warmer or colder than the long-term average a unit of time something is (like how much warmer than average the most recent year was globally). As a result, ocean waters deeper than 500 meters (about 1,600 feet) have a large but still unrealized absorption capacity, said Scripps geochemist Ralph Keeling. The World Ocean is the habitat of 230,000 known species, but because much of it is unexplored, the number of species that exist in the ocean is much larger, possibly over two million. ” A more  Jun 12, 2014 Earth may have underground 'ocean' three times that on surface occur at a much shallower distance, about 80km below the Earth's surface. They teem with life, with perhaps one-quarter of all ocean species depending on reefs for food and shelter. You can start by reducing water pollution and runoff at home Ocean currents are like giant conveyor belts moving huge amounts of water all the time. The rest of its atmosphere was Measuring the Greatest Ocean Depth. A new MIT study shows how changing colors of Earth’s oceans Stiv Wilson of the ocean conservation group 5 Gyres has made a first attempt to tally how much plastic is in the global ocean. Scientists have found a massive volume of water 1,000km inside of our planet, around a third way to Earth’s core: “This water is much deeper than ever found before, at a third of the way to the edge of Earth’s core. Knowing how much heat energy the ocean absorbs and releases is essential for  Jan 31, 2018 There's as much water inside the earth as there is in all of the oceans. For the same reason Earth is an oblate spheroid, the Earth + water would be a slightly larger oblate spheroid. Nonpoint source pollution includes many small sources, like When we think of the ocean, we may think of its power, its wave and the magnificent creatures living it in. Ocean is approximately 3,5 billion. This is still more than 25 times as much water as all rivers and fresh water lakes. " Our ocean has a certain proportion of heavy water to light water. One of the biggest sources is called nonpoint source pollution, which occurs as a result of runoff. Dark blue How much plastic enters the ocean every year? And with roughly 321 million cubic miles of ocean on Earth, researchers are still struggling to assess the scope of our plastic problem. $\endgroup$ – kwknowles Apr 11 '16 Because changes in ocean systems occur over centuries, the oceans have not yet warmed as much as the atmosphere, even though they have absorbed more than 90 percent of the Earth’s extra heat since 1955. And almost all of it—96. Most of it is covered with water. Earth's atmosphere is made mostly of nitrogen and has plenty of oxygen for us to breathe. The origin of Earth's oceans is unknown; oceans are thought to have formed in the Hadean eon and may have been the cause for the emergence of life. If you took all the water on Earth and put it into a ball, it would be about 860 miles wide. Jul 12, 2012 If asked how much of our planet is ocean, most educated people will give a correct approximate of something like the “two thirds. Whether the ocean invariably stabilizes the climate, though, must be doubted. It’s so large that it covers a third of the Earth's surface. “The only genuine way to circumvent this outcome, is to cut our greenhouse gas emissions and limit the acidification of our oceans,” wrote the researchers. This blog post will give a brief overview of how the Earth’s temperature has changed up to the present day.

As of 2013, it takes up 71% of the Earth, houses 99% of the biosphere, and contains some of Earth’s grandest geological features. Looking at our Earth from space, it is obvious that we live on a water planet. The cycle time, technically called "residence time," is short, only about 100 years. When looking at the system in this way, we see that the low carbon dioxide values in the Earth’s atmosphere are a result of the biologically-mediated movement of CO 2 from reactive reservoirs (the atmosphere and ocean) to much less Coral reefs are the most diverse of all marine ecosystems. Though not in the familiar liquid form -- the ingredients for water are bound up in rock deep in the Earth’s mantle This means that fewer diatoms will end up on the ocean floor, resulting in less atmospheric CO2 being removed from our atmosphere and transported for storage in the deep ocean. How much of the global precipitation and evaporation takes place over the ocean? Is it 75% of the total? If the percentage is higher, why does that occur?

Debunking this gets into math which I stink at, regarding refraction. curiositybox. Throughout history, their boundaries have changed and, as of 2000, some countries have recognized and named a fifth ocean. In fact, the amount of salt lost from the ocean and the amount it gains are about the same. In other words, the ocean is a cemetery. ) What happens to the Earth? Not much. instagram. Watch how water vapor moves through the atmosphere and returns to Earth as rain and snow. This heats the land and air during winter and cools it during summer. Meanwhile, the ocean covers almost 3/4 of the surface of Earth. It seems to be their new favorite "evidence" that Earth is not spherical. Less than 1 percent of the Earth's water is fresh water, and 2-3 percent is contained in glaciers and ice caps. These currents are much slower than the surface currents, and in fact have not been measured directly; their existence is however clearly implied by the chemical composition and temperature of water samples taken from various parts of the ocean. Updated every three hours. The oceans are a key element for the existence of life on Earth. In the lab, scientists can determine how much oxygen is produced by a single phytoplankton cell. The Indian Ocean covers about 14% of the Earth’s surface area. Scientists discover an ocean 400 miles beneath our feet that could fill our oceans three times over. S.

This question is an interesting one because, when my friend asked me the other day, I could tell her confidently that not only did science know the answer, science had multiple different ways to quantify that answer, but that I had absolutely no idea what it was. twitter. The fate of our seas is not only up to the government or industry. It is estimated that 93% of the earth’s carbon dioxide is stored in algae, vegetation, and coral under the sea and cycled through the oceans. --- Researchers from Northwestern University and the University of New Mexico report evidence for potentially oceans worth of water deep beneath the United States. While How much of the world’s ocean have humans safeguarded within reserves, refuges and parks to protect marine biodiversity? It is tricky to provide a single clear answer to this question for a number of reasons. The processes that are adding salt to the ocean are very slow. Earth has multiple layers. There is one ocean with many ocean  Jun 22, 2019 Scientists have discovered a sea of fresh water under the ocean Thousands of years ago, glaciers covered much of the planet. In many cases, the bodies of crew members and passengers on shipwrecked vessels stay in the ocean for shockingly long periods of time. Know Your Ocean The ocean covers more than 2/3 of Earth's surface and is a fundamental reason why life exists on Earth—but much of it remains unexplored and under-appreciated. Ocean acidification is an emerging global problem. The ocean is deep: The world's oceans cover 71% of the earth surface and are about 4 km deep on average. You must be able to prove your answer. 05 percent of the ocean floor has been mapped to a level of detail useful for detecting items such as airplane wreckage or the spires Many species that live in the open ocean (or pelagic realm) truly live in an ocean universe. It alludes to the fact that there is a lot of water bound up within the Earth's crust itself (in addition to what is in the oceans): recent studies suggest that 5-10 times the amount of water that is in the oceans is locked up within the top 500-1000 miles of crust. More than 90 percent of the warming that has happened on Earth over the past 50 years has occurred in the ocean. But how much water is there, and where exactly is it held? As well as the obvious places like the oceans, large stores of water can be found in The earth, on the other hand, is very much a water planet. According to the U. How much of the Earth is covered by sea? Some scientists say we should call our planet 'Water' instead of 'Earth', since water covers about 71 percent of the planet's surface. (In fact, I vote we put it directly above the Curiosity rover; that way, it will finally have incontrovertible evidence of liquid water on Mars's surface. The area of the ocean surface is 1. 5 percent—is How Much Water Is There On Earth? Magellan Would Be Shocked : Krulwich Wonders We often think of Earth as mostly water. Ocean Acidification: An Emerging Global Problem. Natural processes and human activities along the coastlines and far inland affect the health of our ocean. The Indian Ocean’s southern border is open to water exchange with the much colder Southern Ocean. Marine life, or sea life or ocean life, is the plants, animals and other organisms that live in the salt water of the sea or ocean, or the brackish water of coastal estuaries. Spheres representing all of Earth's Question: How much of the land on Earth is covered by humans? (Asked by Lynne) Answer: Approximately 10%. I would like to be sure I have considered all the factors. Sea plants, like Posidonia, produce 70% of the oxygen we breathe (1), and the deep waters are home to wildlife and some of the biggest creatures on earth. In 2010 the United States Center for Coastal & Ocean Mapping measured the depth of the Challenger Deep at 10,994 meters (36,070 feet) below sea level with an estimated vertical accuracy of ± 40 meters. It is the only chemical that naturally exists in all three phases (solid, liquid, and gas) in our atmosphere. The waves are lapping on the shore, the Sun is sparkling over the water and there is a refreshing ocean Ocean Worlds Water in the Solar System and Beyond. There are a total of 5 oceans, and they are the Arctic, Pacific, Atlantic, Indian, and the Antarctic Ocean. It’s also in living things. Your favourite beach, maybe. Plastic pollution in the ocean frequently appears as seabird guts filled with cigarette lighters and bottle caps, marine mammals entangled in fishing gear and drifting plastic bags mimicking a gelatinous meal. Water covers 70 percent of Earth's surface. The pressure at the deepest point in the ocean is more than 11,318 tons/sq m, or the equivalent of one person trying to support 50 jumbo jets. • The world’s earliest civilizations developed around the Indian Ocean. But upon close examination, our planet might not be as wet as we think it is. The top ten feet of the ocean hold as much heat as our entire atmosphere The oceans provide 99 percent of the Earth's living space- the largest space in our  An observer at the Earth's equator viewing a mass of water moving north on the surface The fast-moving gyres do not mix much water between ocean basins. But, most of Earth's water, and almost all of the water that people can access, is saline, or salty water. Throughout history, the ocean has been a vital source of sustenance, transport, commerce, growth, and inspiration. Author: Gianna Andrews. The ocean covers most of the globe and plays a crucial role in regulating our climate and atmosphere. The largest ocean on planet Earth is the Pacific Ocean. Like many astronauts, we would likely first notice that the Earth appears blue. The Challenger Deep in the Mariana Trench is the deepest known point in Earth's oceans. The oceans hold about 96. Earth seems to have a lot of water, but it's relatively dry compared to other ocean worlds. Some facts: The ocean makes up 71% of the earth surface. How many percents of Earth's mass are water? I seem to remember some 3 percents, but I don't know. At present, just a quarter of CO2 emissions into the atmosphere are absorbed by the oceans. 7 million (±1. Herschel found that Hartley 2 has half as much heavy water as other comets studied so far. More than 5 trillion plastic particles weighing 268,940 tons are estimated to be floating in Earth’s oceans. Coastal Ocean The sliver of ocean less than 200 meters (650 feet) deep near land accounts for just 7 percent of… Covering over half the Earth’s surface and making up 80% of its living space, or biosphere, these open ocean and deep sea environments are some of the least-explored areas on the planet. Water is an integral part of life on this planet, and NASA plays a major role at the forefront of water cycle research. Our results suggest that some 86% of the species on Earth, and 91% in the ocean, still await description. Things would get pretty Aqua Facts. But what’s down there? How much do we know about it? As it turns out, not very much. Your body is made up mostly of water. The ocean is Earth’s life support. The larger the ocean mass at a certain point of the Earth, the stronger the gravitational strength. Nov 19, 2018 Published in the journal Nature, a team of researchers took an estimate of how much water is being sucked into the Earth's interior through  Apr 10, 2018 Answering the question about how much water on earth is drinkable by how much water is in the ocean, especially when 70% of the earth's  Sep 13, 2016 It is not so much a body of water as it is an underground ocean which This discovery may possibly replace the theory that Earth's oceans are  THE OCEAN. Not only do algae provide much of the Earth's oxygen, they are also the base for almost all marine life. Where do the images come from? How are they they put together? And how often are they updated? Feely is one of a community of oceanographers who have been monitoring Earth’s oceans for decades, trying to figure out how much human-released carbon dioxide the ocean has been soaking up. It is a crescent-shaped trough in the Earth's crust averaging about 2,550 km (1,580 mi) long and 69 km (43 mi) wide. The heat had been generated by the repeated high speed collisions of much smaller bodies of space rocks that continually clumped together as they collided to form this planet. Below we’ve outlined some of the more important water quantity stats such as total water, fresh water and drinkable water numbers. Until the year 2000, there were four recognized oceans: the Pacific, Atlantic, Indian, and Arctic. It would actually take hundreds of thousands of years for the ocean to drain. 3 Increased heat absorption This map depicts the Earth during the last ice age, specifically the Late Glacial Maximum (roughly 14,000 BCE) when the climate began to warm substantially. As a grand total, 94 percent of life on Earth is aquatic. “This research shows that subduction zones move far more water into Earth’s deep interior – many miles below the surface – than previously thought,” said Major. To You may have heard about global warming. At a fundamental level, marine life affects the nature of the planet. As the volume of seawater increases, it causes sea level to rise. • Annually, more than 7,000 humpback whales travel to the waters of Madagascar to breed and give birth. In fact, the tidal effect of the Moon on Earth is more than twice as strong as that of the Sun, even though the Sun's gravitational pull on Earth is around 178 times stronger than that of the Moon. The ocean and lakes play an integral role in many of the Earth's systems including climate and weather. This is much warmer than our earth. The ocean absorbs and distributes heat around the globe, and it acts as a planet Ocean acidification will fry fish populations directly, too, though scientists aren’t yet sure how to predict the effects on the stuff we haul out of the ocean to eat; they do know that in acid What is the Great Pacific Ocean Garbage Patch? A huge sea of plastic trash is swirling in the North Pacific — part of an even broader plastic plague that's growing in oceans worldwide. In Earth's solar system, evidence of subsurface ice, ancient valley networks, and even an ancient ocean occurs on the planet Mars. Hi Margaret, There are still some places on Earth that have not been explored much by people. While wind drives surface ocean currents from the Coriolis effect, temperature and salt gradients mostly influence deep ocean currents. The Pacific Ocean is the largest ocean covering an area of 64,186,000 square miles and the Mediterranean Sea is the largest sea with an area of 1,144,800 square miles. Most of the water cycle studies focus on the processes and changes occurring over land with little emphasis on the ocean. Ocean Pollution and You. 10% of the earth's surface is covered with ice. Jupiter's ice-covered moon Europa has about twice the volume of Earth's liquid water. The planet Earth is a planet of oceans. Many marine organisms are found in the hadal zone, including the  Dec 19, 2018 From the stories those diamonds tell, the mantle is very, very wet, and may contain as much – or more – water than all of the Earth's oceans put  Oct 9, 2014 The entire ocean floor has now been mapped to a maximum resolution of reveal some features of the Earth's crust lurking beneath sea-floor sediments. The total area of the Earth is approximately 510 million square kilometers and the oceans cover about 71 percent of the Earth's surface, which is about 360 million square kilometers. Ocean definition is - the whole body of salt water that covers nearly three fourths of the surface of the earth. With an area of 12 million square kilometers (5 million square miles), the Arctic Ocean is the smallest ocean - more than five times smaller than the Indian and Atlantic oceans. The ocean is the largest solar energy collector on Earth. They moderate the Earth's temperature by absorbing incoming solar radiation (stored as heat energy). ‘How many oceans are there in the world’ is often a common question. The Indian Ocean is south of Asia and the Middle East and east of Africa. When viewed from space, the predominance of Earth’s oceans is readily apparent. Scientists say rock layer hundreds of miles down holds vast amount of water, opening up new If you want to know what organisms are providing the other 50% of oxygen to the earth's atmosphere, walk outside and look for living organisms that are green! Answer 3: Most of the rest of the Earth's oxygen is produced by plants growing on land, particularly in areas with high rainfall (be they tropical or temperate). Our love for surfing has taken us on this incredible journey. Area. Scientists say rock layer hundreds of miles down holds vast amount of water, opening up new Earth may have underground 'ocean' three times that on surface This article is more than 5 years old. Not all of that heating is detectable at the surface because currents move some of the heat to deeper layers of water, where it can "hide" for years or decades. So much of this plastic is ending up in the ocean that in just a few years, we might end up with a pound of plastic for every three pounds of fish in the sea. Space, not so much. The Earth's oceans are all connected to one another. The nature and extent of the deep ocean currents differ in the Atlantic, Pacific, and Indian oceans. org, ) and the estimations for species in the ocean were based on The World's Register of Marine Species (www. The area of the Pacific Ocean, without its surrounding seas, is 165 million square kilometres. They are a long ways from mapping the entire earth. So let's put the ocean-dumping portal far away—say, on Mars. Shorelines are in part shaped and protected by This is a guide about how much water there is on earth. Where is that water located? Is it saltwater or freshwater? Hot Water and Hurricanes Part A: Earth's Ocean: A Storage Unit for Heat. The Earth is a watery place. The record of sea level change can be esti-mated by observing the stable isotope, oxygen-18 in Just how much water is there on Earth? Earth is unique because it has so much water. The trend we see today in the ocean will long outlast the trend we see in the atmosphere. We've all heard about the Texas-sized "garbage patch" swirling in the The Earth is often compared to a majestic blue marble, especially by those privileged few who have gazed upon it from orbit. e. Get an answer for 'What percent of the earth is land and how much is water?' and find homework help for other Geology questions at eNotes Much of Earth’s surface ocean will shift in color by end of 21st century. Today, Ocean And Earth is an international surfing brand that is recognised around the world. The effectiveness of a substance at storing heat Ocean and atmospheric circulation play an essential role in sustaining life by moderating climate over much of Earth's surface. But a study of the complex ecology of the earth's oceans and how deeply connected the ocean is with life on earth, shows we have reason for concern, and not just from the spill in the Gulf of Thus, the ocean surface stabilizes temperature gradients that, in turn, are responsible for much of the atmospheric flow patterns. org. This case study is part of a collection of pages developed by students in the 2012 introductory-level Geology and Human Health course in the Department of Earth Sciences, Montana State University. we need to take our sonar systems much closer to the sea bed using  Apr 5, 2018 About 8 million metric tons of plastic are thrown into the ocean Many marine organisms can't distinguish common plastic items from food. We stock a huge range of surfing products for all types of surfers. Jenny Cheng/Business Insider When Earth cooled enough for water to condense, rain began to fall and filled the deeper parts of Earth's surface until the first oceans formed. These tidal forces cause ocean water to flow into two tidal bulges on opposite sides of Earth; each day, Earth rotates through these bulges. The Pacific Ocean is the largest. Without water, life itself would be impossible. As you know, the Earth is a watery place. NASA & The Water Cycle. With so much of the planet's water tied up in ice, global sea level was more than 400 feet lower than it is today. Last year, a study estimated that around eight million metric tons of our plastic waste The Pacific Ocean is the largest of all the oceans and comprises about 48 percent of all ocean water. The oceans cover 141,600,000 square miles, or 72% of the earth's surface. Water covers more than two-thirds of the Earth’s surface. ETOPO1 is a 1 arc-minute digital representation of Earth's solid surface that integrates land topography and ocean bathymetry from numerous global and regional data sets. Majority of the animals and plants that reside in the So while Europa is only one-fourth the diameter of Earth, its ocean may contain twice as much water as all of Earth’s oceans combined. Some parts of the tropical areas of Earth's oceans receive between 115 and 197 inches of rainfall per year due to massive amounts of water evaporating from the ocean's surface. 8% (361,132,000 sq km) Total land surface area: 29. $\begingroup$ Even with a smooth Earth, the oceans wouldn't be a uniform depth. higher power generation rates may be sustainable over some open ocean areas. Jun 16, 2014 An ocean of water appears to be tied up in minerals of the mantle But finding evidence of melting much farther down, as Dr. Total surface area of earth: 510,072,000 sq km. Accumulating salt in the ocean does not "prove" anything, but it does deal a death blow to evolutionary ideas. The ocean would be shallower at the poles and deeper at the equator by the same ratio as the Earth's axes, so 1/290. While there is only one global ocean, the vast body of water that covers 71 percent of the Earth is geographically divided into distinct named regions. The world’s largest body of water, the Pacific Ocean, covers about one third of the Earth’s surface. Sea surface temperature—the temperature of the water at the ocean surface—is an important physical attribute of the world’s oceans. Oceans account for only a "thin film" of water on the surface. The ocean supports the life of nearly 50 percent of all species on Earth and helps sustain that life providing 20. Maddie Moate explains the extend of the Prochlorococcus and other ocean phytoplankton are responsible for 70 percent of Earth’s oxygen production. The lowest known point on Earth, called the Challenger Deep, is 11,034 m deep, in the Marianas Trench in the western Pacific. Also, the ocean contributes in generating food and oxygen for human being and fighting against climate change by absorbing 93 percent of the carbon dioxide released by human activities. The remaining 95% of the ocean still From this, we can tell that the oceans cover a lot of the Earth but aren’t particularly deep compared to the Earth, and that the rest of the Earth is a good bit more dense than water, not surprising since most rocks don’t float. If all of the continental crust on Earth were eroded down, smoothed out, and distributed evenly across the whole planet, filling in all of the ocean basins and displacing the water therein, how deep The oceans of Earth serve many functions, especially affecting the weather and temperature. a PhD candidate at Columbia University's Lamont-Doherty Earth Observatory, according to  Feb 5, 2015 Ice ages made Earth's ocean crust thicker. Seventy percent of Earth’s surface is ocean, and without it, the other 30 percent would barely be inhabitable. Explain that they will be tossing and catching the globe, recording where their right thumb lands (on water, on land, or for older students on a particular ocean or continent) to get an idea of how much of Earth is covered by water. “The results highlight the important role of subduction zones in Earth’s water cycle. Without this stabilizing influence of the ocean, the weather presumably would be much more fickle. The last estimate was in 1975, when a National Academy of Sciences study Earth with a static atmosphere and no ocean If the earth had a static atmosphere with the same gases it has now, but with little water vapor and no ocean, the average surface temperature of earth would be 67°C (153°F). The peak gold estimates are based on proven and indicated reserves that are reported by public mining companies. They happen over millions of years and that keeps the salt content of the ocean relatively constant. The story of oceans is the story of life. Schmandt did,  In its early history, the Earth's oceans contained significantly more water than they and since the researchers know how much hydrogen was lost to space, they  "The origin of the oceans goes back to the time of the earth's formation 4. While These oceans cover 71 percent of Earth's surface and are interconnected by a series of currents that carry water in continuous cycles throughout all of the oceans. Total water surface area: 70. marvelously-detailed map of the seafloor from NASA’s Earth Observatory be made were actually first published last year finely-wrought ocean maps have Helmholtz Centre for Ocean Research Kiel (GEOMAR). Its largest moon Plastic Oceans International is a global non-profit organization that addresses the issue plastic pollution and how it impacts our waters, sea life and humans. In numbers: The One thing that is clear is that further back in time, CO 2 levels have been much, much higher, and the average global temperatures have also been much higher. This massive ocean is double the size of the Atlantic and contains twice its volume of water. Lethal Effects of Ocean Pollution. The answer above does not state that water out = water in. The deep Earth holds about the same amount of water as our oceans. Earth is much bigger than other ocean worlds in the solar system, but Europa, Pluto, and others have bigger oceans of liquid water. Oceans cover 71% of the Earth's surface, and contain 97 percent of the planet's water. marinespecies. (3. In addition, as Earth has warmed, much of the excess energy has gone into heating the upper layers of the ocean. It is said that humans have managed to explore only about 5% of the ocean floor. Written when the speaker, Little Dog, is in his late twenties, the letter unearths a family The deep ocean. Less than one percent of all the The World Ocean is the habitat of 230,000 known species, but because much of it is unexplored, the number of species that exist in the ocean is much larger, possibly over two million.

This means that the salinity of the oceans does not gradually increase, or even change greatly, but is actually in a state of equilibrium. Trade winds carry this evaporated water to different areas where it cools and then falls back into the ocean. 50 to 70 % of our oxygen comes from the ocean. 95% of the ocean remains unexplored, most of which is considered the deep ocean. Understanding the ocean ecosystem is important for children, as it affects everyone. Mar 2, 2016 That means that most of the living space on Earth is in the deep sea. interactions with other components of the Earth system. ” Oceans Are Absorbing Almost All of the Globe’s Excess Heat more than 90 percent of the excess heat retained by the Earth as a result of increased The near-surface ocean takes only We think of Earth as watery – the blue planet. 3 billion cubic km of water. This represents a Plastics in the Ocean Affecting Human Health. In the Spring of 2000, the International Hydrographic Organization delimited a new ocean, the Southern Ocean (it surrounds Antarctica and extends to 60 degrees latitude). For eons, the world’s oceans have been sucking carbon dioxide out of the atmosphere and releasing it again in a steady inhale and exhale. ScienceDaily. List of featured articles about Earth and Geography / Oceans and Seas / Oceans / Southern Ocean: Ocean, Antarctica, Pacific Ocean, Atlantic Ocean, Indian Ocean, Southern Ocean, Jules-Sébastien-César Dumont d'Urville, Sir George Hubert Wilkins, Drake Passage, Antarctic Circumpolar Current Salt has accumulated in the ocean over a very long period of time from rivers, the seabed, and vents from deep in the earth that contain these same dissolved minerals. The time series below shows the five-year average variation of global surface temperatures. Look at the earth spinning around. An ocean is a body of water that composes much of a planet's hydrosphere. much of this water however is still Indian Ocean. You are concerned with freshwater to serve your life's every need. How much gold is left in the ground? Nobody really knows. 6 billion years. The surface temperature of the world’s oceans varies mainly with latitude, with the warmest waters generally near the equator and the coldest waters in the The ocean and lakes play an integral role in many of the Earth's systems including climate and weather. The ocean absorbs most of this "anthropogenic heat" because: Water has a high heat capacity: It takes much more heat to warm 1 liter of water than it does to warm the same volume of air (or most other substances). how much of the earth is ocean
