The Mariana Trench, in the Pacific Ocean, is the deepest location on Earth.
What is the biggest trench in the ocean?
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.
Why is the 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.
Is there a place deeper than Mariana Trench?
The deepest point in the Tonga trench, known as the Horizon Deep, considered to be the second deepest point on earth after the Challenger Deep and the deepest trench of the Southern Hemisphere.
Has anyone been to 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.
What is the deepest trench in the world?
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.
Is there a bottom to 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. … The Challenger Deep is nearly three times deeper than that.
Who owns Mariana Trench?
Because Guam is a U.S. territory and the 15 Northern Mariana Islands are a U.S. Commonwealth, the United States has jurisdiction over the Mariana Trench.
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.
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).
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.
Is there a Megalodon in the Mariana Trench?
According to website Exemplore: “While it may be true that Megalodon lives in the upper part of the water column over the Mariana Trench, it probably has no reason to hide in its depths. “There’s no food for it down there, and no other shark species are known to thrive that deep.
What would happen to your body in the Mariana Trench?
The pressure from the water would push in on the person’s body, causing any space that’s filled with air to collapse. (The air would be compressed.) So, the lungs would collapse.
What animals live in Mariana Trench?

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.
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.
