Why is the Mariana Trench so deep?
One reason the Mariana Trench is so deep, he added, is
because the western Pacific is home to some of the oldest seafloor in the world—about 180 million years old
. Seafloor is formed as lava at mid-ocean ridges. When it’s fresh, lava is comparatively warm and buoyant, riding high on the underlying mantle.

How deep can humans go in the ocean?
How deep in the ocean can the human body go? That means that most people can dive up to a
maximum of 60 feet
safely. For most swimmers, a depth of 20 feet (6.09 metres) is the most they will free dive. Experienced divers can safely dive to a depth of 40 feet (12.19 metres) when exploring underwater reefs.
What would happen to a human at the bottom of 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. … The nitrogen would bind to the parts of the body that need to use oxygen, and the person would literally suffocate from the inside out.
Is the Kola Superdeep borehole deeper than the Mariana Trench?
In 1970, Soviet engineers began their deepest hole project. … The hole itself is 7.5 miles deep (12 km), but interestingly, it is only 9 inches wide in diameter. The Kola Superdeep Borehole
is deeper than the Mariana Trench

How long does it take to get to the bottom of the Mariana Trench?
Pre-expedition estimates put the Challenger Deep descent at
about 90 minutes
