Continental Drift

This video describes the evidence Alfred Wegener used to formulate his continental drift hypothesis and examines why this idea did not gain wide acceptance when it was originally proposed. Wegener pursued four lines of evidence to support continental drift and the existence of the supercontinent, Pangaea. His evidence included the fit of the continents, matching features between now separated land masses, reconstructions of past climates, and the distribution of several fossil species.
