Mariana Trench - Deepest Part of the Ocean 海洋最深处

The Mariana Trench is located in the Pacific Ocean, just east of the 14 Mariana Islands (11°21′ N 142° 12′ E) 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.
