  • 9/20/12 BR: What do you think Will Chicago ever have a volcano? How are mountains formed? Why do earthquakes happen? Today: The Earths Crust & Continental Drift

  • Continental DriftEarths crust is broken up into plates which float around on magma and bump into each other.Plates move at a rate of between to 4 inches annually

  • Pangaea Super Continent from which all continents grew

  • Continental Drift Plates come together or spread apart at plate boundries.Convergence- when 2 plates come together, forming mountainsSubduction- when 1plate slides under the otherDivergence- when magma rises to the surface, creating new ocean floor- sea floor spreadingTransform- when 2 plates slide against each other- fault lineContinental rift- when a continent is pulled apart

  • Assignment (25 Points)- Due ThursdayUsing information from today draw each type of plate boundry. Make sure to label each type of boundry.
