How many gallons of water is in the ocean?
352 quintillion gallons The ocean contains 352 quintillion gallons of water! Water enters the ocean from rivers and melting ice and leaves the ocean into the atmosphere through evaporation.
How much liters of water is in the ocean?
Volumes. The volume of water in all the oceans together is approximately 1.335 billion cubic kilometers (1.335 sextillion liters, 320.3 million cubic miles).
Do we know 20% of the ocean?
Despite its size and impact on the lives of every organism on Earth, the ocean remains a mystery. More than 80 percent of the ocean has never been mapped, explored, or even seen by humans.
Do we know 5% of the ocean?
In fact, most of the waters remain unexplored, uncharted and unseen by our eyes. It might be shocking to find out, but only 5% of the ocean has been explored and charted by humans. The rest, especially its depths, are still unknown.
How deep does the ocean go down?
35,876 feet The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam. Challenger Deep is approximately 10,935 meters (35,876 feet) deep.
How deep is the ocean in miles?
2.3 miles They also found one of the deepest zones, in the western Pacific, the Mariana Trench which stretches for 1,580 miles (2,540 kilometers). Today scientists know that on average the ocean is 2.3 miles (3.7 kilometers) deep, but many parts are much shallower or deeper.
Is there an ocean under the ocean?
Scientists discover an ocean 400 miles beneath our feet that could fill our oceans three times over. After decades of theorizing and searching, scientists are reporting that they've finally found a massive reservoir of water in the Earth's mantle — a reservoir so vast that could fill the Earth's oceans three times over …
Could there be monsters in the ocean?
Sea monsters really DO lurk beneath the waves, scientists claim. From krakens to gigantic sea serpents, terrifying monsters of the deep have haunted the imaginations of generations of mariners. Now experts in marine life claim sea monsters might actually exist.
Why is the ocean blue?
The ocean is blue because water absorbs colors in the red part of the light spectrum. Like a filter, this leaves behind colors in the blue part of the light spectrum for us to see. The ocean may also take on green, red, or other hues as light bounces off of floating sediments and particles in the water.
How deep the ocean is?
The average ocean depth is 3.7 kilometers (2.3 miles). That's 2.74 kilometers (1.7 miles) down! The average depth of the ocean is about 3,688 meters (12,100 feet).
Is there a bottom to the ocean?
In the Pacific Ocean, somewhere between Guam and the Philippines, lies the Marianas Trench, also known as the Mariana Trench. At 35,814 feet below sea level, its bottom is called the Challenger Deep — the deepest point known on Earth.
What is under the ocean?
Scientists discover an ocean 400 miles beneath our feet that could fill our oceans three times over. After decades of theorizing and searching, scientists are reporting that they've finally found a massive reservoir of water in the Earth's mantle — a reservoir so vast that could fill the Earth's oceans three times over …
What is in the bottom of the ocean?
The bottom of the deep sea has several features that contribute to the diversity of this habitat. The main features are mid-oceanic ridges, hydrothermal vents, mud volcanoes, seamounts, canyons and cold seeps. Carcasses of large animals also contribute to habitat diversity.
Does the ocean have a bottom?
At 35,814 feet below sea level, its bottom is called the Challenger Deep — the deepest point known on Earth. In fact, to put it into perspective, think about the Titanic, which was found 12,600 feet below the surface of the Atlantic Ocean — nearly 2.4 miles down.
How did water get on Earth?
Far from the Sun, where temperatures are low, water formed icy objects such as comets, while closer to the Sun water reacted with rocky materials to form hydrated minerals. It's thought that the mostly likely way that planet Earth inherited its water was from asteroids and comets crashing into it.
What did NASA see in the ocean?
Here, Kepler's supernova remnant was captured in a NASA image. Traces of rare forms of iron and plutonium have been found at the bottom of the Pacific Ocean, after some kind of cataclysm in outer space created this radioactive stuff and sent it raining down on our planet.
Why is the ocean scary?
Fear of the ocean is actually one of several "prepared" fears, which are grounded in our survival instincts. Or, as he puts it: "The ocean's a dangerous place." It's pretty justifiable to find the ocean scary because of rip currents, sharks, or the possibility of drowning.
What is the scariest sea?
The Devil's Sea Is the Bermuda Triangle's Twin The Devil's Sea is called the Bermuda Triangle of the Pacific, and it's not difficult to understand why: this area off the coast of Tokyo is also known for strange disappearances and shipwrecks, including the MV Derbyshire, the biggest ship ever lost at sea.
Why is the ocean red?
As the name suggests, the bloom of algae often turns the water red. HABs have been reported in every U.S. coastal state, and their occurrence may be on the rise. HABs are a national concern because they affect not only the health of people and marine ecosystems, but also the 'health' of local and regional economies.
How deep has a human gone in the ocean?
35,853 feet Vescovo's trip to the Challenger Deep, at the southern end of the Pacific Ocean's Mariana Trench, back in May, was said to be the deepest manned sea dive ever recorded, at 10,927 meters (35,853 feet).
Is there a lost city under the sea?
Geologists know that there are two kinds of "lost cities" underwater: those that were made by humans, and those that weren't. The latter turns out to be the case for one such city, discovered by tourists diving off the Greek island of Zakynthos in 2014.
What did NASA find in the ocean?
Here, Kepler's supernova remnant was captured in a NASA image. Traces of rare forms of iron and plutonium have been found at the bottom of the Pacific Ocean, after some kind of cataclysm in outer space created this radioactive stuff and sent it raining down on our planet.
Is there just one ocean?
There is only one global ocean. Historically, there are four named oceans: the Atlantic, Pacific, Indian, and Arctic. However, most countries – including the United States – now recognize the Southern (Antarctic) as the fifth ocean. The Pacific, Atlantic, and Indian are the most commonly known.
Can it snow on the ocean?
The short answer is yes– there is such a thing as marine snow and snow on the ocean, but it's not the snow you're thinking of when you build a snowman or go skiing.
Who owns the ocean floor?
The oceans have no apparent surface features — just a flat, vast, briny expanse. They're also all connected; the world's five oceans are technically one single ocean that covers 71 percent of the planet (source: NOAA). This makes it difficult to divide, and so ultimately, you own the oceans.
Who created Earth?
Formation. When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle, and a solid crust.
How old is the ocean?
The ocean formed billions of years ago. At this time, about 3.8 billion years ago, the water condensed into rain which filled the basins that we now know as our world ocean.
Why can’t we go to the bottom of the ocean?
“The intense pressures in the deep ocean make it an extremely difficult environment to explore.” Although you don't notice it, the pressure of the air pushing down on your body at sea level is about 15 pounds per square inch. If you went up into space, above the Earth's atmosphere, the pressure would decrease to zero.
At what depth is the ocean dark?
Such a minuscule amount of light penetrates beyond a depth of 200 meters that photosynthesis is no longer possible. The aphotic zone exists in depths below 1,000 meters. Sunlight does not penetrate to these depths and the zone is bathed in darkness.
What has NASA found in the ocean?
Here, Kepler's supernova remnant was captured in a NASA image. Traces of rare forms of iron and plutonium have been found at the bottom of the Pacific Ocean, after some kind of cataclysm in outer space created this radioactive stuff and sent it raining down on our planet.
