What is the longest ocean trench in the world?

The Mariana Trench, in the Pacific Ocean, is the deepest location on Earth. According to the Exclusive Economic Zone (EEZ), the United States has jurisdiction over the trench and its resources. Scientists use a variety of technologies to overcome the challenges of deep-sea exploration and explore the Trench.

Which is the longest trench?

The Mariana Trench or Marianas Trench is located in the western Pacific Ocean about 200 kilometres (124 mi) east of the Mariana Islands; it is the deepest oceanic trench on Earth. It is crescent-shaped and measures about 2,550 km (1,580 mi) in length and 69 km (43 mi) in width.

How deep has a human gone in the ocean?

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 animals live in Mariana Trench?

  • Dumbo Octopus.
  • Deep-sea Dragonfish.
  • Barreleye Fish.
  • Benthocodon.
  • Seadevil Anglerfish.
  • Goblin Shark.
  • Deep-sea Hatchetfish.
  • Frilled Shark.

What would happen to your body in the Mariana Trench?

The pressure from the water would push in on the person’s body, causing any space that’s filled with air to collapse. (The air would be compressed.) So, the lungs would collapse.

Is there a monster in the Mariana Trench?

A second prehistoric monster that may have well lived in the Mariana Trench is this giant marine Mosasaur known as hainosaurus, which scientists think grew up to 12 meters long – about the same length as an average megalodon.

Has a megalodon been found in the Mariana Trench?

‘No. It’s definitely not alive in the deep oceans, despite what the Discovery Channel has said in the past,’ notes Emma. ‘If an animal as big as megalodon still lived in the oceans we would know about it. ‘

What’s at the bottom of 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. … Challenger Deep is the deepest point of the Marianas Trench.

Which ocean has the deepest trenches?

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 36,200 feet deep.

Where are deep sea trenches found?

Deep-sea trenches generally lie seaward of and parallel to adjacent island arcs or mountain ranges of the continental margins. They are closely associated with and found in subduction zones—that is, locations where a lithospheric plate bearing oceanic crust slides down into the upper mantle under the force of gravity.

What part of the ocean is the deepest?

Challenger Deep

At what depth will water crush you?

At about 10–12 meters (33–40 feet) of depth, pressure of water column above you (1 extra atmosphere of pressure per 10 meters) will compress air spaces in your body by half, with lungs compressing the most by the absolute volume.

How far 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 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.
