What goes on during an earthquake? Who came up with the theory of plate tectonics? What can the fossil record tell us about the evolution of life on Earth? These are all fine questions, and students and educators with a thirst for geological knowledge will find the answers to these (and many more) questions in the "Earth Revealed" television series. Offered as part of the Annenberg Media website, the 26-part series includes such episodes as "Geologic Time", "Mountain Building", and "The Birth of a Theory". As with many of the Annenberg Media offerings, visitors can view entire episodes here, and they can also take a look at a list of additional resources.
