    • Antonio snider pellegrini
      French geographer and scientist that theorize that the west coast of Africa and the east coast of south America had once beed connected as a single continent
    • Pangaea
      Around 250 million years ago, during the mesozoic era or the age of dinosaurs, all the land on earth was connected as one Gian continent
    • Panthalassa
      A superocean that surrounds the supercontinent
    • Alfred lothar Wegner
      A German meteorologist and geophysicist, famous for proposing the continental drift theory in 1910
    • Plate tectonics theory
      Explains that Earth's outer shell is broken up into several slabs or rock plates
    • The four main layers of Earth
      • Core
      • Lower mantle
      • Upper mantle
      • Crust
    • Core
      Made up of heavy metals
    • Crust
      Lightest sedimentary
    • Two types of crust
      • Continental crust
      • Oceanic crust
    • Lithosphere
      Upper solid part of the mantle
    • Asthenosphere
      Broken into several plates that "float" on a soft layer of partially molten rock
    • Plate boundaries
      The areas where these plates meet
    • Three types of plate boundaries
      • Divergent
      • Convergent
      • Transform fault/ conservative boundary
    • Divergent boundary

      Plates move apart and create space between them for the rising magma
    • Seafloor spreading
      Responsible for the formation of oceanic rift valleys
    • Rift valley
      Low-lying regions of land formed by the separation of tectonic plates
    • Convergent boundary

      A region where two plates collide
    • Subduction
      When two plates collide, the edge of one plates bends downward and sink beneath the opposite plate
    • Subduction zone
      The area where subduction occurs
    • Oceanic - continental convergence
      The edge of the oceanic lithosphere bends and sinks to the asthenosphere where viscous magma flows
    • Oceanic trench

      The process of subduction forms a long, narrow depression on the ocean floor
    • Marianas trench
      The most well known trench in the world
    • Challenger deep
      The deepest point of the Marianas trench
