The Mariana Trench is the deepest oceanic trench on Earth.

It is located in the western Pacific Ocean about 200 kilometres (124 mi) east of the Mariana Islands. The maximum known depth is 10,984 metres (36,037 ft) (6.825 miles) at a point known as the Challenger Deep.

If Mount Everest were placed into the trench at this point, its peak would still be under water by more than two kilometres (1.2 mi).

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).

In 2009, the Marianas Trench was established as a United States National Monument.

Microbes have been found within the mud at the bottom of the trench.
