Plate Tectonics - Where is the deepest ocean? o Challenger Deep ? the Mariana Trench (also called the Challenger Deep) is located in the Pacific Ocean, just east of the 14 Mariana Islands near Japan ? the Mariana Trench is 11,033 meters (36,201 feet ~ 7 miles) deep ? hydrostatic pressure is 16,000 psi ? Why is the Challenger Deep so deep? ? plate tectonics - Plate tectonics o describes the large scale motions of Earth?s lithosphere o a theory that Earth?s lithosphere consists of large, rigid plates that move horizontally in response to the flow of the asthenosphere beneath them, and that interactions among the plates at their borders cause most major geologic activity, including the creation of oceans, continents, mountains, volcanoes, and earthquakes - Seismic waves ? waves that travel through the Earth, most often as the result of a tectonic earthquake, sometimes from an explosion o P waves ? the primary or compression wave in a seismic wa...
