Across
  1. 2. A theory that states that Earth's surface is made up of rigid plates that move to each other.
  2. 4. Forms where tow plates collide.
  3. 5. The most popular super continent.
  4. 7. The circulation of material caused by differences in temperature and density.
  5. 8. The outermost rock layer.
  6. 10. When two plates collide and the denser plate sinks bellow the other.
  7. 12. A state in which magnetized objects will point north.
  8. 13. Mountain ranges in the middle of the oceans.
  9. 15. The process by which new oceanic crust form along a mid-ocean ridge and older crust away from the ridge.
  10. 16. A hypothesis that says the continents are in constant motion.
Down
  1. 1. Forms where two plates slide past each other.
  2. 3. Forms where two plates separate.
  3. 6. As a slab sinks, it pulls on the rest of the plate with a force.
  4. 9. Type Hint here, all the answers don't include spaces except for number 3 which includes a dash.
  5. 11. A state in which magnetized objects would reverse direction and orientate themselves to point righ.
  6. 14. The same state as the normal polarity but it reverses direction.
