  1. Earth Science Historical IntroductionContinental Drift

  2. What do you notice about the continents?

  3. 1596 – Abraham Ortelius, a mapmaker, suggested the Americas were “torn away from Europe and Africa…by earthquakes and floods”

  4. The Continental Drift Theory • Meteorologist Alfred Wegener • 1915 published “The Origins of Oceans and Continents” • proposed Pangaea

  5. Supercontinent “Pangaea” • Idea based on ‘fit’ of the continents

  6. Wegener’s Evidence • Fossil evidence • Tropical plant fossils in Antarctica • Rock type and structural similarities • Matching mountain ranges on different continents • Paleoclimatic evidence • Glacial deposits in Africa

  7. Fossil Evidence

  8. Criticism of Drift Theory • Theory not accepted in Wegener’s lifetime • He could not explain how such large land masses could be moved Last photo of Wegener before his death in 1930 on a meteorological expedition in Greenland
