Lesson 2

  1. 1. Plate Tectonics
  2. 2. Is Earths crust moving
  3. 3. Is Earths crust movingGeologist is a scientist who examines rocks
  4. 4. Is Earths crust movingGeologist is a scientist who examines rocksTheory of Continental Drift: Wegener’s theory of thecontinents moving apart
  5. 5. Is Earths crust movingGeologist is a scientist who examines rocksTheory of Continental Drift: Wegener’s theory of thecontinents moving apartContinental drift theory was helped to be proven bythe fossils left behind
  6. 6. Is Earths crust movingGeologist is a scientist who examines rocksTheory of Continental Drift: Wegener’s theory of thecontinents moving apartContinental drift theory was helped to be proven bythe fossils left behindSupercontinent: PANGEA
  7. 7. What causes the Ocean floor to spread
  8. 8. What causes the Ocean floor to spreadPlate Tectonics explain how forces cause the OceanFloor to spread
  9. 9. What causes the Ocean floor to spreadPlate Tectonics explain how forces cause the OceanFloor to spreadMagma: is hot melted rock that causes tension or astretch or push on the plates Cooling magma forms the mid-ocean ridge
  10. 10. How do Mountains form
  11. 11. How do Mountains form Compression: Squeezing or pushing together of the crust this produces folded mountains
  12. 12. How do Mountains form Compression: Squeezing or pushing together of the crust this produces folded mountains Shear: Plates rub past another this produces faults
