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 tectonics has had on our understanding of Earth's geological history, as we have become aware of our planet's ever-changing nature.

The web page is located within Teachers'Domain, an online educational resource produced by WGBH Boston.
