Plate Tectonics Basics

For an introductory college-level earth sciences class: a review of the basics of plate tectonics, including the three boundary types: convergent, divergent, and transform; ocean plate subduction; continent-continent convergence; seafloor spreading; and mantle convection. There is also a discussion of the layers and components of ocean crust (in relation to how it formed at seafloor spreading centers), and terrane accretion in subduction zones (as a way that continents grow).

Content within this video is based on information available in any standard introductory college oceanography or geology textbook, such as Essentials of Oceanography -- Trujillo and Thurman -- OR Essentials of Geology -- Tarbuck and Lutgens -- Pearson Publishing.
