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