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.
Rocky Mountain Trench The Rocky Mountain Trench, also known as The Valley of a Thousand Peaks or simply the Trench, is a large valley in the northern part of the Rocky Mountains. It is both visually and cartographically a striking physiographic feature extending approximately 1600 km from Flathead Lake, Montana to the Liard River, just south of the British Columbia-Yukon border near Watson Lake, Yukon. The trench bottom is 3-16 km (2–10 miles) wide and ranges from 600-900 metres (2,000–3,000 feet) above sea level. The general orientation of the Trench is an almost uniform 150/330 degree geographic north vector and has become convenient for north/south aviators.
