  1. The Theory of Continental Drift Continental Drift Discovery

  2. The World

  3. ALFRED WEGENERTHEORY OF CONTINENTAL DRIFT Found evidence for PANGAEA and proposed the theory of continental drift.

  4. Continental Drift (p95 red book, 182 in Sciencesaurus) • Theory that continents were once part of a single landmass that broke apart and have moved to their present locations. • can drift apart from one another and have done so in the past For more information about what the continents looked like throughout the Earth’s History go to: htttp://www.ucmp.berkeley.edu/geology/anim1.html

  5. Pangaea Pangaea is the name given to the single landmass that was present 200 million years ago Can you name the continents in Pangaea? http://kids.earth.nasa.gov/archive/pangaea/Pangaea_game.html

  6. Recreating Wegener’s Discovery Create your own Pangaea using the same evidence Wegener used. K12: Plate Tectonics

  7. WEGENER’S EVIDENCE Continents “fit together” like puzzle pieces

  8. WEGENER’S EVIDENCE • Fossil Evidence • fossils are remains of living things that lived long ago. • similar fossils have been discovered in matching coastlines on different continents.

  9. WEGENER’S EVIDENCE

  10. WEGENER’S EVIDENCE • Mountains • Some mountain ranges on different continents seem to match. • Ex: ranges in Canada match Norway and Sweden • Ex: Appalachian Mtn. match UK mtn

  11. WEGENER’S EVIDENCE • Climatic evidence such as glaciers in areas that are now close to the Equator

  12. Evidence of Continental Drift Satellites used tomeasure the movement of continents • Laser Geodynamics Satellite (LAGEOS)

  13. The Plates Move…So what now? Which way? • 50 million years
