What tectonic plate is located west of a trench which reaches a maximum-known depth of 10994 m?
Mariana Trench The Mariana Trench or Marianas Trench is the deepest part of the world's oceans. It is located in the western Pacific Ocean, an average of 200 km to the east of the Mariana Islands, in the Western Pacific East of Philippines. It is a crescent-shaped scar in the Earth's crust, and measures about 2550 km long and 69 km wide on average. It reaches a maximum-known depth of 10994 m (± 40 m ) at a small slot-shaped valley in its floor known as the Challenger Deep, at its southern end, although some unrepeated measurements place the deepest portion at 11034 m . If Mount Everest were dropped into the trench at this point, its peak would still be over 1.6 km underwater. In 2009, Marianas Trench was established as a United States National Monument.
Tectonics of the Tian Shan The Tian Shan is a mountain range in central Asia that extends through western China, Kazakhstan, and Kyrgyzstan. The Tian Shan is 2800 km long, and up to 7400 m high. Throughout the Tian Shan there are several intermontane basins separated by high ranges. Plate tectonic theory makes the assumption that deformation is concentrated along plate boundaries. However, active deformation is observed in the Tian Shan, far from plate boundaries. This apparent contradiction of plate tectonic theory makes the Tian Shan a key place to study the dynamics of intracontinental deformation.
