Watch Plate Tectonics & Earthquakes

Find out why the solid-seeming earth is actually a changing body, constantly destroying and rebuilding itself. Tectonic plates' movements are clearly demonstrated as the source of these alterations through exciting live-action and computer graphic images. Viewers learn how seismology helps reveal the earth's structure, how the plates' collisions create earthquakes, and how the Richter scale works. Other earthquake-related terms such as amplitude, magnitude, aftershocks, subduction, and epicenter are illustrated in clear detail, and the program shows why plate tectonic theory is the foundation of modern geology.

Plate Tectonics & Earthquakes is a 2007 special interest movie with a runtime of 14 minutes.
