Which is the deepest ocean in the world?

The average depth of the ocean is about 12,100 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.

How deep has a human gone in the ocean?

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).

Which ocean is least deepest?

With an area of about 6.1 million square miles , the Arctic Ocean is about 1.5 times as big as the United States. It is bordered by Greenland, Canada, Norway, Alaska, and Russia. The average depth of the Arctic Ocean is 3,953 feet and it is 18,264 feet at its deepest point.

What is the biggest and deepest ocean in the world?

The Pacific Ocean is the largest and deepest of the world ocean basins. Covering approximately 63 million square miles and containing more than half of the free water on Earth, the Pacific is by far the largest of the world’s ocean basins.

Which ocean is deepest on average?

However, in terms of average depth, the Pacific Ocean is the deepest. Though calculations vary, it is estimated that the entire ocean floor averages about 4,280 meters (14,042 ft), which is over 500 m (1640 ft) deeper than the global average of 3,700 meters (12,100 ft).

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 deep can a human dive before being crushed?

Human bone crushes at about 11159 kg per square inch. This means we’d have to dive to about 35.5 km depth before bone crushes. This is three times as deep as the deepest point in our ocean.

Which ocean is the coldest?

The Arctic Ocean is the smallest, shallowest, and coldest part of the ocean.

Which ocean is shallowest?

Arctic Ocean. The Arctic Ocean is the smallest and shallowest of the world’s five major oceans.

What is at the bottom of the ocean?

The seabed (also known as the seafloor, sea floor, or ocean floor) is the bottom of the ocean, no matter how deep.

Which ocean is most dangerous?

Finally, let’s look at one of the biggest and most dangerous seas to sail in the world: the Indian Ocean. To its north lies Asia, to the east Australia, and to the west Africa. In the middle lies an ocean spanning some 20% of the Earth’s watery surface.

Which ocean is called the warmest ocean on Earth?

Located between Africa to the west and Asia to the north, Australia in the east and Antarctica in the south, the Indian Ocean is the warmest ocean in the world.

Which country has the largest sea in the world?

What would happen if you were teleported to the bottom of the ocean?

So nothing would happen if you were teleported to the bottom of the Mariana Trench for one nanosecond, although you may come back wet. Short answer: Not much. Light, which travels at just over 186,000 miles per second in a vacuum, only travels about one foot in a nanosecond.

How many Mt Everest can fit in the ocean?

If you could transpose Mt. Everest on the Challenger Deep (lowest point in the Mariana Trench), there’ll still be approximately 2146 meters of seawater over the summit (depending on the state of the sea).

Why are oceans so deep?

The extreme depth of the Mariana Trench and other oceanic trenches is caused by subduction – where on the boundary of two converging tectonic plates, one descends down into Earth’s mantle, creating a deep trough.
