Audience: Students; Grades: K-5; Subject: Science. (2008) The fascinating geologic processes of mountain building, seafloor spreading and volcanoes are a few examples of the power of plate tectonics. Footage filmed on-location in Iceland, the Canadian Rockies, and Crater Lake help viewers understand the theory of plate tectonics. Colorful animations illustrate the movement of tectonic plates and the role this plays in the development of geologic features. Other terminology includes: theory of continental drift, mid-ocean ridge, plate boundaries, subduction, convergent boundary, and divergent boundary.
