Pangaea

  1. 1. 1 2 3 4 5 6 7 8
  2. 2. Pangaea: The Super-Continent Created by Mr. Raponi
  3. 4. The Father of the Continental Drift Theory <ul><li>In 1915, the German geologist and meteorologist </li></ul><ul><li>________________ first proposed the theory of </li></ul><ul><li>________________ Drift </li></ul><ul><li>This idea states that parts of the Earth's crust slowly drift atop a </li></ul><ul><li>_______________ core. </li></ul>Alfred Wegener Continental Liquid BIG AL
  4. 5. Big Al’s Big Discovery
  5. 6. Pangaea <ul><li>Wegener thought that there was a gigantic super continent </li></ul><ul><li>_______ million years ago </li></ul><ul><li>Pangaea was an area consisting of all of Earth's land masses. It existed from the </li></ul><ul><li>______________ through </li></ul><ul><li>____________ Periods. It began breaking up during the late Triassic period. </li></ul>225 Permian Jurassic
  6. 7. Pangaea: 200 million years ago <ul><li>1. ______________ </li></ul><ul><li>2. South America </li></ul><ul><li>3. ______________ </li></ul><ul><li>4. ______________ </li></ul><ul><li>5. Asia </li></ul><ul><li>6. ______________ </li></ul><ul><li>7. Antarctica </li></ul><ul><li>8. _______________ </li></ul>1 2 3 4 5 6 7 8 North America Europe Africa Australia India
  7. 8. Continental Drift <ul><li>The rock plates that the continents sit on moved, the super-continent broke up and began to move apart. </li></ul><ul><li>This continental </li></ul><ul><li>___________ is far from over. The Earth's surface is constantly moving and reforming, but so slowly that you or I can't observe it ourselves. </li></ul>Drift
  8. 9. What Did It Look Like?
  9. 10. Speed of Movement <ul><li>Below the land, there is a layer of rock called the Deep </li></ul><ul><li>____________, which is hot enough to be fairly soft. The plates seem to float on this soft rock, altering the shape of the Earth’s surface </li></ul><ul><li>The plates are moving at a speed that has been estimated at </li></ul><ul><li>_________ cm per year </li></ul>Moving Area Mantle 1-10
  10. 11. Inside of The Earth
  11. 12. TYPES OF PLATE MOVEMENT <ul><li>When two plates collide, some crust is destroyed in the impact and the plates become smaller. The results differ, depending upon what types of plates are involved. </li></ul>
  12. 13. Oceanic Plate and Continental Plate <ul><li>When a thin, dense oceanic plate collides with a relatively light, thick continental plate, the oceanic plate is forced under the continental plate; this phenomenon is called </li></ul><ul><li>___________________. </li></ul><ul><li>It essentially boils down to the fact that the continental plate is much larger and stronger than the little oceanic plate, and the smaller of the two is eaten up by the larger one. </li></ul>Subduction
  13. 14. What is Subduction?
  14. 15. Two Continental Plates <ul><li>When two </li></ul><ul><li>_______________ plates collide, </li></ul><ul><li>_______________ are created as the colliding crust is compressed and pushed upwards. </li></ul>Continental Mountains
  15. 16. Two Continental Plates Collide The Land Above The Plates Rises, Creating Mountains
  16. 18. Lateral Slipping Plate Movement <ul><li>When two plates move sideways against each other, there is a tremendous amount of </li></ul><ul><li>_____________ which makes the movement jerky. </li></ul><ul><li>The plates slip, then stick as the friction and pressure build up to incredible levels. When the pressure is released suddenly, and the plates suddenly come apart, this is an </li></ul><ul><li>_________________. </li></ul>Friction Earthquake
  17. 19. Earthquakes
  18. 21. <ul><li>3-2-1 : </li></ul><ul><li>3 important terms to remember. </li></ul><ul><li>2 ideas or facts you would like to know more about. </li></ul><ul><li>1 idea, process, or skill you think you have mastered. </li></ul>Ticket To Leave
