The Plunging Sea Floor and Deep-Sea Trenches
Lecture no. 7 from the course: Oceanography: Exploring Earth's Final Wilderness
Taught by Professor Harold J. Tobin | 32 min | Categories: The Great Courses Plus Online Science Course
Investigate subduction zones, where oceanic crust plunges beneath an overriding tectonic plate. These margins are associated with deep-sea trenches, earthquakes, tsunamis, and volcanoes. Examine other features, such as hotspots, which are a mid-plate phenomenon that includes the Hawaiian Islands chain.
