Who reached 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.

What is the most famous ocean trench?

The Aleutian Trench, in the North Pacific Ocean , and the deepest, most famous one in the world, the Marianas Trench off the coast of the Marianas Islands in the Southeast Pacific. These are all places where oceanic plates are subducting beneath continental plates.

What is the deepest oceanic trench caused by?

The Mariana trench contains the deepest part of the world’s oceans, and runs along an oceanic-oceanic convergent boundary. It is the result of the oceanic Pacific plate subducting beneath the oceanic Mariana plate.
