The Challenger Deep in the Mariana Trench is the deepest known point in Earth’s oceans. In 2010 the United States Center for Coastal & Ocean Mapping measured the depth of the Challenger Deep at 10,994 meters (36,070 feet) below sea level with an estimated vertical accuracy of ± 40 meters.
Which is the biggest deep?
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.
What is the deepest depth in the world?
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 the second deepest depth in the world?
The deepest point of the Tonga Trench, the Horizon Deep at23.25833°S 174.726667°W, is 10,800 ± 10 m (35,433 ± 33 ft) deep, making it the deepest point in the Southern Hemisphere and the second deepest on Earth after the Challenger Deep in the Mariana Trench.
What is the 2nd deepest part of the ocean?
The Tonga Trench is the second-deepest trench in the world, reaching 35,700 feet (about 10,900 meters) at its deepest point. (The Mariana Trench off the coast of Guam is the deepest trench in the world, measured 35,756 feet (10,890 m) at its deepest point.)
Is there a bottom to the ocean?
The seabed (also known as the seafloor, sea floor, or ocean floor) is the bottom of the ocean, no matter how deep. All floors of the ocean are known as ‘seabeds’.
How deep in the ocean can we go?
The deepest point ever reached by man is 35,858 feet below the surface of the ocean, which happens to be as deep as water gets on earth. To go deeper, you’ll have to travel to the bottom of the Challenger Deep, a section of the Mariana Trench under the Pacific Ocean 200 miles southwest of Guam.
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 lives at the bottom of the ocean?
However, there are more than 200 species of anglerfish, divided into four groups: goosefish, batfish, frogfish, and deep-sea angler. Only females possess the iconic, bioluminescent angling apparatus. Most live at the bottom of the Atlantic and Antarctic Oceans, sometimes as far as a mile below the surface.
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. … Light, which travels at just over 186,000 miles per second in a vacuum, only travels about one foot in a nanosecond.
What is the shallowest ocean?
The Arctic Ocean is the smallest and shallowest of the world’s five major oceans.
What are the 5 deepest trenches in the world?
The Five Deeps Expedition was the first to reach the deepest point in each of the Earth’s five oceans: the Puerto Rico Trench in the Atlantic, South Sandwich Trench in the Southern Ocean, Java Trench in the Indian Ocean, Challenger Deep in the Pacific and Molloy Deep in the Arctic.
How deep is the Molloy Deep?
It is the location of the deepest point in the Arctic Ocean. The outer rim of the trench is at a depth of 2,700 m (8,900 ft) and contains about 600 km2 inside the rim, descending to approximately 5,550 m (18,210 ft) at its greatest depth.
Where are the deepest trenches on Earth?
The deepest trench in the world, the Mariana Trench located near the Mariana Islands, is 1,580 miles long and averages just 43 miles wide. It is home to the Challenger Deep, which, at 10,911 meters (35,797 feet), is the deepest part of the ocean.
What are the 3 deepest ocean trenches?
Deepest oceanic trenches
| Trench | Ocean | Maximum Depth |
|---|---|---|
| Mariana Trench | Pacific Ocean | 10,984 m (36,037 ft) |
| Tonga Trench | Pacific Ocean | 10,882 m (35,702 ft) |
| Philippine Trench | Pacific Ocean | 10,545 m (34,596 ft) |
| Kuril–Kamchatka Trench | Pacific Ocean | 10,542 m (34,587 ft) |
What is the largest 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. All of the world’s continents could fit into the Pacific basin.
