Across
  1. 4. rigid layer which is broken into segments
  2. 7. The series of wave-like ripples or bends formed during mountain building
  3. 8. rock reshapes without breaking
  4. 13. are formed from pre-existing rocks through heat and pressure.
  5. 15. is about 84% of Earth’s volume
  6. 16. occurs when all the unconsolidated materials settle in one area
  7. 18. is the rigid outermost layer of Earth that is composed of crust and the uppermost layer of the mantle.
  8. 19. squeezing stress
  9. 20. This is a force that causes hotter, less dense material to force itself up through a ridge.
Down
  1. 1. This is the pulling of oceanic lithosphere downward at subduction zones.
  2. 2. are formed from pre-existing rocks and fossils of organisms.
  3. 3. are formed from cooling of molten magma.
  4. 5. is a model used to describe how rocks are formed
  5. 6. show age differences based on plate movements.
  6. 9. a dynamic planet composed of interacting subsystems
  7. 10. is the semi-solid layer below the asthenosphere.
  8. 11. parallel but opposite directions
  9. 12. causes breakage
  10. 14. is a process of breaking down rock into smaller pieces
  11. 17. rock returns to original shape
