Transcript

  • 1. How does this animation explain The Theory of Continental Drift?
  • 2. ReviewReview Continental drift 1. Continent shape 2. Fossil evidence 3. Rock evidence 4. Mountain evidence 5. Glacial scars
  • 3. Plate TectonicsPlate Tectonics Two parts of the theory: Part One: Lithosphere - the solid layer of the Earth, Is broken up into crustal plates
  • 4. Plate TectonicsPlate Tectonics Crustal plates - large pieces of crust 7 main plates and several smaller ones Continents and ocean floors rest on the plates
  • 5. Plate TectonicsPlate Tectonics Part Two: Crustal plates “float” on the upper part of the mantle Like rafts on a lake
  • 6. Source of MovementSource of Movement Convection current – the movement of a fluid caused by temperature difference
  • 7. Source of MovementSource of Movement Gravity
  • 8. Plate TectonicsPlate Tectonics Explains how the continents move Also explains natural events like: Earthquakes Mountain formation Volcanoes
