What is meaning of Mariana Trench?
What is meaning of Mariana Trench?
noun. a depression in the ocean floor of the Pacific, S and W of the Mariana Islands: site of greatest known depth of any ocean. 36,201 feet (11,034 meters) deep.
Is the Mariana Trench hot?
It’s Hot and It’s Cold The water there tends to range between 34 to 39 degrees Fahrenheit. But what’s surprising is how hot the water can get, too. There are hydrothermal vents throughout the trench.
Is the Mariana Trench an abyss?
Incorrectly, it states the Laurentian abyss is the deepest point on earth; rather this is Challenger Deep, a part of the Mariana Trench. The abyss is seen again in the sequel Revenge of the Fallen where the Decepticons come to revive Megatron.
Who owns Mariana Trench?
the United States
Who reached Mariana Trench?
The first two people to reach the Challenger Deep, located in the south end of the Mariana Trench about 190 miles southwest of Guam, were Don Walsh and Jacques Picard in 1960.
What animals live in Mariana Trench?

- Scientific name: Grimpoteuthis.
- Comb Jellies.
- Scientific name: Ctenophora.
- Benthocodon.
- Scientific name: Benthocodon hyalinus.

- Scientific name: Argyropelecus Gigas.
- Scientific name: Opisthoproctidae.
Is there a place deeper than Mariana Trench?
Originally Answered: Is there a place deeper than the Mariana Trench? Yes, but you can’t go there. It’s only 9 inches wide. It’s the Kola Superdeep Borehole, 12,262 meters deep, around 1300m deeper than the Challenger Deep in the Mariana Trench.
Is the Mariana Trench still forming?
The Mariana Trench was formed through a process called subduction. Earth’s crust is made up of comparably thin plates that “float” on the molten rock of the planet’s mantle. Today, the majority of the Mariana Trench is a U.S. protected zone as part of the Marianas Trench Marine National Monument, established in 2009.
How cold is the Mariana Trench?
At the bottom of the trench, the water column above exerts a pressure of 1,086 bars (15,750 psi), more than 1,071 times the standard atmospheric pressure at sea level. At this pressure, the density of water is increased by 4.96%. The temperature at the bottom is 1 to 4 °C (34 to 39 °F).
Can humans go to the Mariana Trench?
It’s been a record-breaking expedition in more ways than one. 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).
What is the farthest underground that humans have ever been?
The deepest mining operation, which would be the deepest humans have gotten into the crust, is the TauTona Mine , a gold mine in South Africa. It reached 3.9 kilometers (2.4 miles) underground in 2008. At that depth the temperature is 55 °C (131 °F), so massive air conditioning is required for men to work there.
How hot is it 1 mile underground?
Geologists calculate that, for every mile you dig beneath the Earth’s surface, the temperature rises 15º F and the pressure increases simultaneously at a rate of about 7,300 pounds per square inch. Violations of the 15-degrees-per-mile rule are unknown and constitute the notorious forbidden zone.
How deep can a human go underground?
Humans have drilled over 12 kilometers (7.67 miles) in the Sakhalin-I. In terms of depth below the surface, the Kola Superdeep Borehole SG-3 retains the world record at 12,262 metres (40,230 ft) in 1989 and still is the deepest artificial point on Earth.
Why did they stop digging the Kola Superdeep borehole?
Drilling was stopped in 1992, when the temperature reached 180C (356F). This was twice what was expected at that depth and drilling deeper was no longer possible. Following the collapse of the Soviet Union there was no money to fund such projects – and three years later the whole facility was closed down.
Is the Kola Superdeep borehole deeper than the Mariana Trench?
The hole itself is 7.5 miles deep (12 km), but interestingly, it is only 9 inches wide in diameter. The Kola Superdeep Borehole is deeper than the Mariana Trench, the deepest point in the ocean.
Which country has the deepest man made hole?
Russia
What is the deepest hole dug by hand?
Woodingdean Well
Is it possible to dig to China?
To dig to China, you’d need to start your journey from Chile or Argentina — the location of China’s antipode (or opposite point on Earth). You would need a super-powered drill to get through rock and metal within Earth’s three layers. First, there’s the Earth’s crust.
What happens if you dig too deep in the earth?
To make things more difficult, as they drill deeper into the Earth, they’ll encounter extreme temperatures, possibly in excess of 1,000 degrees Fahrenheit (538 degrees Celsius), and fantastic amounts of pressure — as much as 4 million pounds per square foot in the vicinity of the mantle.
What’s at the bottom of the world’s deepest hole?
So what did scientists find at the bottom of the hole? First, there’s lots of water down there—though it may be formed from stray oxygen and hydrogen atoms squeezed out of rock minerals. Second, there are plankton fossils as deep as 6700 meters. Third, it’s incredibly hot—more than 350 °F.
What is the deepest point in the ocean?
Challenger Deep
What would happen if you drilled to the Earth’s core?
You would just float, being pulled equally by gravity in all directions. That said, you would still be traveling at an unparalleled speed, so you’d zip right through that awesome feeling pretty quickly. As you pass through Earth’s center, still moving at 6 miles per second, the process would begin to reverse.
