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) |

What is the second deepest trench in the world?
The Tonga Trench is an oceanic trench located in the southwestern Pacific Ocean. It is the deepest trench in the Southern hemisphere and the second deepest on Earth. The fastest plate-tectonic velocity on Earth is occurring at this location, as the Pacific Plate is being subducted westward in the trench.
Is there deeper than Mariana Trench?
After all, it was only in 1997 that researchers discovered the Sirena Deep, which is also located in the Mariana Trench, which they measured at 35,210 feet, less than a thousand feet shallower than the Challenger Deep.
What is the Earth’s deepest point called?
Then explain to students that the Mariana Trench is the deepest part of the ocean and the deepest location on Earth. It is 11,034 meters (36,201 feet) deep, which is almost 7 miles.
What is the deepest place on Earth?
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 is the deepest point in the ocean?
Challenger Deep
What causes deep ocean trenches?
Trenches are formed by subduction, a geophysical process in which two or more of Earth’s tectonic plates converge and the older, denser plate is pushed beneath the lighter plate and deep into the mantle, causing the seafloor and outermost crust (the lithosphere) to bend and form a steep, V-shaped depression.
What is the shallowest ocean?
The Arctic Ocean is the smallest and shallowest of the world’s five major oceans.
Which is the deepest lake in the world?
Lake Baikal (5,315 feet [1,620 meters])
Lake Baikal, in Siberia, holds the distinction of being both the deepest lake in the world and the largest freshwater lake, holding more than 20% of the unfrozen fresh water on the surface of Earth.
What is the smallest ocean?
The Arctic Ocean is the smallest of the world’s five ocean basins. A polar bear walks on the frozen surface of the Arctic Ocean. The freezing environment provides a home for a diverse range of creatures. With an area of about 6.1 million square miles , the Arctic Ocean is about 1.5 times as big as the United States.
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.
Why is the Mariana Trench so dangerous?
Because of its extreme depth, the Mariana Trench is cloaked in perpetual darkness and the temperature is just a few degrees above freezing. The water pressure at the bottom of the trench is a crushing eight tons per square inch—or about a thousand times the standard atmospheric pressure at sea level.
Do sharks live in the Mariana Trench?
the megalodon shark can still live in the depths. … if the megalodon is out there its gotta be in the Mariana trench, just because it was a live 200000 years ago doesn’t mean its still extinct who knows it could none has had PROOF that its EXTINCT.
