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.
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).
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.
Why is Mariana trench so deep?
Why is the ocean so deep here? The Mariana Trench is located at a convergent plate boundary. Here two converging plates of oceanic lithosphere collide with one another. At this collision point, one of the plates descends into the mantle.
What is 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.
How deep can a human dive before being crushed?
How Deep Can a Human Dive Before Being Crushed? There is no fixed depth where we can say for sure that a diver will be crushed once they cross a certain depth. Most recreational divers don’t generally go beyond 130 feet, but commercial divers manage to reach depths of 2,000 feet with the help of atmospheric suits.
At what depth will water crush you?
Human beings can withstand 3 to 4 atmospheres of pressure, or 43.5 to 58 psi. Water weighs 64 pounds per cubic foot, or one atmosphere per 33 feet of depth, and presses in from all sides. The ocean’s pressure can indeed crush you.
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.
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.
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.
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.

How cold is the Mariana Trench?
At the bottom of the trench, the water column above exerts a pressure of 1,086 bars (15,750 psi), more than 1,071 times the standard atmospheric pressure at sea level. At this pressure, the density of water is increased by 4.96%. The temperature at the bottom is 1 to 4 °C (34 to 39 °F).
Why is Black Sea not a lake?
If you compare to the Mediterranean there is less salt in the Black Sea, and there is less salt in Caspian Sea if you compare with Black Sea. … – During ice age most of the time Black Sea was cut off from the oceans due to evaporation, that means it should have been called Black Lake until about 9000 years ago.
Why is Clear Lake so dirty?
Runoff from surrounding hills both supplies water for Clear Lake and drags sediment, pollutants and other items into the body. Runoff from surrounding hills both supplies water for Clear Lake and drags sediment, pollutants and other items into the body.
Where is the biggest lake in the world?
The largest lake in the world by a long shot is the Caspian Sea – a name that hints at a past when it was contiguous with the ocean around 11 million years ago. This massive saline lake, which is nearly the same size as Japan, borders five countries: Kazakhstan, Russia, Turkmenistan, Azerbaijan, and Iran.
