How Deep Is The Mariana Trench?

The Mariana Trench is a deep sea trench just off the East coast of the Phillipines and it is the deepest trench in the oceans of the world. The deepest part of the Mariana Trench is the Challenger Deep, so named after the exploratory vessel HMS Challenger II; a fishing boat converted into a sea lab by the Swiss scientist Jacques Piccard. At this point, the Mariana Trench is 6033.5 fathoms deep, which is 11 033 meters, or 36 201 feet deep.

To be able to imagine the actual depth of the Mariana Trench, consider this; if Mount Everest, which is the tallest point on Earth at 8 850 meters (29 035 feet), picked up and put down inside the Mariana Trench, there would still be 2 183 meters (7 166 feet) of water left above it.

The Mariana Trench was formed when the oceanic crust, a heavy dense crust, collided with the continental crust, which is lighter. At the collision, the heavier oceanic plate, moves downwards towards the molten mantle of the Earth and the ocean trench is formed at the bottom of the trench created by the subducting ocean crust.

The maximum depth of the Mariana Trench is 10,911 meters. The Mariana Trench is till date the deepest know trench of the world. The trench is located at the western North Pacific Ocean, and lies towards the east and south of the Mariana Islands near Guam.

The trench basically is a border where two tectonic planes meet. The bed of the trench is farther below sea level than the height of Mount Everest. The trench was first inspected in 1951 by Royal Navy container Challenger which gave the deepest end of the trench its name, 'The Challenger Deep'. Using the echo sounding technology, Challenger II determined the depth of the area which was recorded at 5,960 fathoms.

At the core of the Mariana trench, water exerts a pressure of 1,086 bars, over the time period of 1,000 times the standard atmospheric pressure at normal sea level.
