This video uses clay models to demonstrate effects of continental drift. Mountains forming at convergent faults, sea floor created at divergent faults, island chains forming at hot spots, and formation of volcanoes at subduction zones are shown. Th...is selection provides visual of these concepts for students. (01:10)

Some of the most influential theories began as seemingly implausible notions. This is not to say that the scientific community embraces every new idea that comes along. Alfred Wegener, the scientist who first proposed the theory of continental drift,... learned that the hard way. This video segment adapted from A Science Odyssey chronicles the unveiling of Wegener's theory and shows how compelling evidence is sometimes dismissed when it supports new or incomplete theories. Closed captioning included. Run time 03:55.

Contrary to what most geologists thought less than 100 years ago, we live on a dynamic planet. Earth's surface has changed in countless ways during the 4.6 billion years since it formed, and it continues to change today. This video segment adapted fr...om Discovering Women looks at some of the geologic processes that have shaped the landscape near Lake Mead, Nevada, and suggests that these processes may be causing North America to slowly break apart. Closed captioning included. Run time 02:13.

In the early 1900s, most geologists thought that Earth's appearance, including the arrangement of the continents, had changed little since its formation. This video segment adapted from Discovering Women describes the impact the theory of plate tecto...nics has had on our understanding of Earth's geological history, as we have become aware of our planet's ever-changing nature. Closed captioning included. Run time 02:21.

According to theory of plate tectonics, Earth is an active planet — its surface is composed of many individual plates that move and interact, constantly changing and reshaping Earth's outer layer. Volcanoes and earthquakes both result from the moveme...nt of tectonic plates. In this interactive activity produced for Teachers' Domain with images from NASA, see the relationship between earthquakes and volcanoes and the boundaries of tectonic plates.

This episode discusses the scientific theory of plate tectonics, in which the Earth’s crust is subdivided into a series of large and small tectonic plates. Convergent, divergent or transform boundaries are discussed and demonstrated with brittle grah...am crackers and icing to illustrate the motions of the plates at these boundaries. A second demonstration consisting of heating cream in a pan, representing convecting upper mantle, driving a relatively brittle layer of cocoa powder (the Crust). (06:02)
