GeoBasics: Plate Tectonics DVD

Study the Ever-Shifting Plates of Earth

Our planet’s crust or lithosphere is not a single solid layer. Though we know this now, it was not always the common understanding. Beginning with Alfred Wegener’s hypothesis of continental drift, the program shows the evolution of thought behind the Earth’s major and minor plates, types of plate boundaries, and the concepts of spreading and subduction. Earthquakes and volcanoes are also addressed. A viewable/printable instructor’s guide is available onlinefrom this program, which relates to National Science Education Standards, National Educational Technology Standards, and Standards for the English Language Arts. Duration: 25 minutes.
