The Mariana Trench is located in the Pacific Ocean, just east of the 14 Mariana Islands (11″21′ North latitude and 142″ 12′ East longitude ) near Japan.   As you probably already know, it is the deepest part of the earth’s oceans, and the deepest location of the earth itself.  It was created by ocean-to-ocean subduction, a phenomena in which a plate topped by oceanic crust is subducted beneath another plate topped by oceanic crust.

Fact-The Mariana Trench is 11,033 meters (36,201 feet), (6033.5) fathoms deep. The Pressure at the deepest part of the Mariana Trench is over 8 tons per square inch. The Mariana Trench is 2, 542 km (1,580 miles) long and 69 km (43 miles) wide.
