What percentage of Earth's surface is covered by water?

According to some figures, the consensus is that 70.8% of the Earth's surface is covered by water; 29.2 % is covered by land. Other figures suggest the percentage of Earth's surface covered by water is 71.11%; the percentage covered by land is 28.89%. Only 3% of that water is fresh water, the rest is saltwater.

The amount of Earth covered by water is exactly 71.13%

70.78% of the Earth is covered in water.

Land covers 29.22 percent of the Earth's surface. This is about 57.5 million square miles (149 x 106 square kilometers). Water covers the other 70.78 percent of the Earth's surface. This is about 139.4 million square miles (361 x 106 square kilometers).

It's just over 7/10

The answer is simple, water covers about 70% of the earth's surface, and has a volume of about 1.4 billion km3

Furthermore about 97% of earth's water is stored in the oceans.

About 71 percent of the Earth's surface is water-covered, and the oceans hold about 96.5 percent of all Earth's water. But water also exists in the air as water vapor, in rivers and lakes, in icecaps and glaciers, in the ground as soil moisture and in aquifers, and even in you and your dog.
Yes the water cover the earth 75vpercent.

What is the deepest point in the ocean and where is it located?

In the Western Pacific, south of Japan and north of New Guinea, and to the east of the Mariana Islands is the lowest elevation of the surface of the Earth's crust. Known as the Mariana Trench, the trench is nearly 1,580 miles (2,550 kms) long and 43 miles (69 km) wide, its deepest part is known as the Challenger Deep. Named after the Royal Navy ship, HMS Challenger that first sounded it back in December 1872 to May 1876, who recorded a depth of 31,614 feet, (9,636 metres).

Subsequent expeditions have lowered and raised the depth. In 1951, another Royal Navy vessel also called Challenger reported the depth as 35,761 ft, (10,900 m).

In 1957, the Russian vessel Vityaz reported a depth of 36,200 ft, (11,034 m).

In 1984, the Japanese reported a depth of 35,840 ft, (10,924 m)

Since then the National Geographic has published the maximum depth at 36,200 feet (11,034 metres) in 1995.

Also in 1995, the Japanese reported a depth of 35,798ft (10,911 m). This is thought to be the most accurate readings.

In June 2009, an American expedition reported the maximum depth of 35,994 ft (10,971 m).

In 2010, the US Center for Coastal & Ocean Mapping measured its depth at 36,070 ft (10,994 m).

So if we take the 1995 Japanese readings as the most accurate, that is 6.78 miles (10.91kms) straight down. If Mount Everest was placed there, its summit would still be one mile below the surface. The pressure down there is a staggering 15,966 pounds (7.24 metric tonnes) per square inch, or roughly 1,086 times the pressure we live with at sea level.

More men have walked on the Moon's surface than have visited the bottom. As of the time of writing (December 2009) only two men have visited the bottom, and that was back in 1960. Don Walsh and Jacques Piccard rode the bathyscape Trieste to the bottom, where they remained for 20 minutes. It looks like that record will stand for a long time, as no one has a manned DSV (that is in the public's knowledge) capable of reaching those depths.
Yes, the Mariana trench is the deepest trench, also not to be rude but it's trench not treanch.

What is the difference between estuaries and coral reefs?

They are completely different. An estuary is where a river joins the sea or, it is an outflow of freshwater into the ocean or sea. A coral reef is a strictly marine environment created by thousands of tiny organisms over thousands of years. It consists of the calcium skeletons of reef building organisms overlaid with living corals, anemones, clams, snails, fish etc etc.

What is the air pressure at sea level?

Atmospheric pressure at sea level is the result of the force of gravity on the matter above sea level (the atmospheric gases). The amount of matter is not constant due to the height and density of the atmosphere (mostly due to temperature and water content/humidity).

Unfortunately for the student, there are many, many different units for measuring atmospheric pressure. Standard air pressure at sea level is most easily defined as 1 atmosphere, or 1 atm.

In terms of an international (ISO) standard, it is defined to be 101325 Pa or 101.3 kPa (kilo-Pascals) at a temperature of 15 °C. In meteorology outside of the United States (and sometimes among scientists in the USA), hPa (hectoPascal) is most commonly used (=1013.25 hPa)

Note that a Pascal is also equal to N/m2 - Newtons per square meter, while 1 hpa = 1 mb (millibar) which is convenient for meteorologists, as noted above. Therefore, standard atmospheric pressure also = 1.01325 bar = 1013.25 mb.

The metric value is commonly accepted to be 760mmHg(millimeters of mercury, also "torr"). "Millimeters of Mercury" is a measure that come from a kind of barometer (pressure meter) that uses a column of mercury in a glass tube to measure pressure: The higher the pressure, the taller the column of mercury.

In American units of measure, it's 29.92 in. Hg (inches of mercury) or 14.696 psi (pounds per square inch). This means that, at sea level, the weight of air pressing on every square inch of something is almost 15 pounds.

Something to think about: If you had 1 square inch of room-temperature mercury that was 29.92" tall, it would weigh ... 14.696 pounds!

Again, these are the average atmospheric pressures only at sea level. Pressure drops as we gain altitude; for instance, in Denver, approximately 1 mile above sea level, atmospheric pressure drops to approximately 12.2 PSI or 841.4 millibar.

If you were at sea level, the weight of the air pressing down on you would be 1.03 kilograms per square centimeter.or 1013.25 millibars.

What are the 4 oceans called?

the Pacific, Indian, Atlantic, and Arctic oceans.

Another Answer:

There are five oceans; the Pacific, Indian, Atlantic, Arctic, and Southern. Some geographers disagree on this point, wanting to call the Southern Ocean an extension of the Pacific, Indian, and Atlantic. Others further feel that the Arctic is part of the Atlantic.

Why is ocean water saltier in warm places?

When water evaporates it leaves salt behind causing water in warmer areas that have more evaporation to have saltier water.

The Mediterranean Sea (from observation via thermal images from space) is one of the saltiest seas, also the Red Sea (to a lesser extent). Both the Dead Sea and the Great Salt Lake are so salty that most people find it easy to float. Lake Assal is considered the saltiest body of water outside of Antarctica.

The Northern Pacific is at the other end of the spectrum, containing relatively lower ocean salinity.

Water evaporation at phenomenal rate in warmer places causes accumulation of salt in respective area. Add to the fact that the warmer the water the higher the maximum saturation capacity and you have very salty seas. These are the main two factors of water salinity.

There are areas in the world where fresh water mixes with salt water, thus reducing the salinity. These areas include: 1) The mouths of rivers; 2) The melting ice pack, such as in the Arctic and Antarctic; and 3) Areas around Greenland, where the glaciers 'calve' off, making icebergs. This list is not all inclusive.

The Difference Between

What is the difference between a sea and an ocean?

A sea is part of an ocean that is partially surrounded by land. If it is totally surrounded, then it's called an inland sea. An ocean is a body of salt water with no boundaries and limitless volume. It's limitless because with no boundaries, definitive quantity cannot be deduced. Between the two, the ocean is the larger of the two. Oceans are enormous when compared to any sea. The largest sea in the world is the Mediterranean with a total area of 965,000 square miles which is much smaller than the smallest ocean in the world the Arctic at 5,427,000 square miles. There are only five oceans in the world namely the Pacific, the Atlantic, the Indian, the Southern and the Arctic while there are dozens of seas around the world. Seas being close to land are generally much shallower than oceans and therefore it is possible for plant and animal life to thrive on a sea bed because it is generally lit up by light. Ocean beds are much much deeper, and support only very basic life forms like bacteria and shrimp that feed on them in isolated parts. This is because no light reaches there and the pressure are such that marine life as we popularly conceive cannot survive. Some idea of the depth of an ocean can be had from the fact that the Pacific Ocean has an average depth of 3790 meters or 12,430 feet. The average depth of the Mediterranean Sea on the other hand is 4690 feet.
An extension of saline water on the earth is called a sea.

large sea areas are called oceans.

Swimming

Why do people get thirsty after swimming in the ocean?

The ocean is very salty and salt dries out your mouth giving you the feeling that you are thirsty.

Actually, the reason is two fold:

(1) As with any exercise, you sweat while you swim, as a way to help cool your body, as exercise has increased the body temperature. It may seem amazing, but a typical competitive swimmer can easily lose several pounds of water weight during a typical day's 2 hour swim practice. This loss of water means you feel thirsty, in the same way that you would after an extended run. Look at most swim practices - swimmers will actually keep bottles of water at the end of the pool, and drink from them periodically.

(2) The human skin is not a waterproof barrier. The ocean, which contains a high concentration of salt, is out-of-balance with the water inside of the human body. As two adjacent volumes of a liquid with difference concentrations of a solute will try to balance themselves out, the low-salt water inside of the human body attempts to balance itself with the high-salt ocean water. Unfortunately, salt cannot be absorbed through the human skin, which means that the water inside the human body attempts to "balance" out the ocean water by diluting it (which, given the volume difference, is impossible). In effect, the salty ocean water "sucks" out water from the inside of the human body, as the two volumes attempt (futilely) to balance the salt concentration. This processes is slow, but not that slow. Thus, it is easy to become dehydrated while swimming in salt water, as the ocean literally sucks out the water from your body. A human being will die of dehydration while stuck swimming in the ocean far faster than they would by being in the middle of the hottest desert on earth.

Exacerbating (2), most people in the ocean manage to swallow a non-trivial amount (a pint or more) of ocean water if they spent any amount of time in anything other than completely calm water. The extremely high salinity of said water accelerates the dehydration process, as it sucks out water from the body into the digestive tract (to be eventually excreted in a couple of hours).

What happens to coral reefs if they get too cold?

Some shallow-water coral reefs can grow in temperate waters where the temperatures are not as warm as the tropical waters off the coasts of Australia, the Bahamas, etc. but even these cannot withstand temperatures under 81 degrees Fahrenheit (with the exception of some in the Persian Gulf). Most corals die when they get too cold as they are extremely sensitive and do not have the capability to warm themselves up. Deep-water coral reefs have adapted to withstand the cold temperatures of deeper waters and thus do not face this problem.
