  8. granite
    type of rock that makes up the continental crust
  9. plasticity
    ability of a solid to flow, or change shape
  10. lithosphere
    topsmost solid part of the earth, which is composed of the crust (7 major plates) and some of the mantle
  11. mantle
    layer of the earth that extends from the bottom of the crust to the outer core
  12. asthenosphere
    layer of the earth directly beneath the lithosphere and the 7 majot plates float on it
  13. hanging wall
    block of rock above the fault
  14. stress
    forces that pull and push upon the crust
  15. shearing
    stress that pushes rock in two opposite directions
  16. compression
