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.
