What is the deepest sea?

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.

Which is the deepest sea in the world?

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 deepest ocean in miles?

At the southern end of the Mariana Trench lies a relatively small slot of exquisite depth: Challenger Deep. Challenger Deep plunges to 10,924 meters (35,840 feet; 6.788 miles).

What is the top 3 deepest ocean?

Ans : The Pacific Ocean, the Atlantic Ocean, and the Indian Ocean are the three deepest Oceans in the world. The average depth of the Atlantic Ocean along with its adjacent seas is 10,932 ft or 3,332 m. 13002 ft or 3963 m is the average depth of the Indian Ocean.

Which ocean is coldest?

A “supercoolometer”, a device that sounds like it should be used to measure hipsters, has found the coldest seawater on Earth, under Antarctic sea ice.

This Incredible Animation Shows How Deep The Ocean Really Is

Which ocean is the shallowest?

The Arctic Ocean is the smallest and shallowest of the world's five major oceans. This water body is completely surrounded by the continents of Asia, North America, Europe and the island of Greenland.

How deep can we go in 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.

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).

Have we hit the deepest part of the ocean?

At nearly seven miles, the deepest part is a mile longer than Mount Everest is tall. Both manned and unmanned vessels have reached these depths, called Challenger Deep.

What animal lives in the Mariana Trench?

Deep sea amoebas, shrimp-like creatures, and sea cucumbers live at the bottom of the Mariana Trench. Mariana Trench animals include xenophyophores, amphipods, and small sea cucumbers (holothurians) which all dwell at the bottom of the ocean's deepest depression.

Has anyone reached the bottom of the Mariana Trench?

While thousands of climbers have successfully scaled Mount Everest, the highest point on Earth, only two people have descended to the planet's deepest point, the Challenger Deep in the Pacific Ocean's Mariana Trench.

Why is the ocean 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.

Does anything live in the Mariana Trench?

The Mariana Trench is deeper than Mount Everest is tall and anything living there has to survive the cold water and extremely high pressure. Some animals, including the deep-sea crustaceans Hirondellea gigas , do live there —and they have recently had a human visitor.

Which ocean is longest?

The Pacific Ocean is the largest and deepest of the world ocean basins.

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.

What is the mystery of the Mariana Trench?

The depth of the Mariana Trench makes it one of the deadliest places on the planet. Forever covered in darkness, water temperature is below 0 degree Celsius. What makes it near impossible for life as we know it to exist is the extreme water pressure. 8 tonnes per square inch increases with depth.

Which ocean is hottest?

The warmest ocean in the world is the Indian Ocean.

How far into the earth have we gone?

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.

How does the bottom of the ocean look?

All the way down At depths below about 4,000 m (2.5 mi), the seafloor is called the abyssal plain. It is essentially flat because the rugged topography of the underlying basaltic crust is draped in sediment that can be up to five km (three mi) thick. The abyssal plains cover 25% of the Earth's surface.

Can you drink melted sea ice?

Ocean water freezes at a lower temperature than freshwater.

When seawater freezes, however, the ice contains very little salt because only the water part freezes. It can be melted down to use as drinking water.

Which ocean has the worst storms?

The Pacific Ocean generates the greatest number of tropical storms and cyclones. The most powerful storms, sometimes called super typhoons, occur in the western Pacific. The Indian Ocean is second in the total number of storms, and the Atlantic Ocean ranks third.

How cold is the Arctic ocean?

The temperature of the surface water of the Arctic Ocean is fairly constant at approximately −1.8 °C (28.8 °F), near the freezing point of seawater.

What is the youngest ocean?

The Atlantic Ocean is the youngest of the five oceans, having formed during the Jurassic Period approximately 150 million years ago following the breakup of the supercontinent Pangaea. The Atlantic Ocean is the second-largest ocean on Earth, accounting for one fifth of the Earth's surface and 29% of the Earth's water.
