  1. 2. scientist who came up with the theory of continental drift
  2. 4. plate boundary where two plates slide against each other
  3. 5. plate boundary where two plates move away from each other
  4. 7. energy release often caused by transform boundaries
  5. 9. divergent plate boundaries, also known as __________ plate boundaries due to new crust being created
  6. 10. in convection, less dense warmer material does this
  7. 11. process by which new crust forms
  8. 12. convergent plate boundaries, also known as __________ plate boundaries because lithosphere returns to the mantle here
  9. 14. landform created when two continental plates converge
  10. 15. large pieces of the lithosphere that slowly drift
  11. 17. in convection, denser cooler material does this
