Across
  1. 1. occurs when two plates moves toward each other
  2. 4. when the hanging wall moves up
  3. 5. folds in adjacent layers with different wavelengths and shape
  4. 7. strata dip away from axial center
  5. 11. is a force acting on a rock per unit area, Any rock can be strained. Strain can be elastic, brittle, or ductile
  6. 12. occurs when the hanging wall moves down relative to the foot wall
  7. 16. a geologic process in which tectonic plates—large slabs of Earth's lithosphere—split apart from each other
  8. 17. strata dip toward axial center
  9. 18. bottom of the ocean
  10. 20. a fracture or zone of fractures between two blocks of rock.
Down
  1. 2. occurs when two plates moves away
  2. 3. strata dip toward center in all direction
  3. 6. a break in earths crust where older rocks are pushes above younger rock
  4. 8. a fault along a plate boundary where the motion is predominantly horizontal.
  5. 9. youngest strata in the center
  6. 10. strata dip away from center in all direction
  7. 13. is the result of gravitational forces acting on the young, raised oceanic lithosphere around mid-ocean ridges
  8. 14. force exerted by a cold, dense oceanic plate plunging into the mantle due to its own weight.
  9. 15. angular fold with straight limbs and small hinges
  10. 19. oldest strata in the center
