Across
  1. 1. Supercontinentnal mass
  2. 3. Pull in which the subducting crust is heavy enough to pull the rest of itself over the edge
  3. 4. Is Considered "The classic" force and is the new curst forming at divergent boundaries that pushes the plates
  4. 6. Theory that Earth's surface is dramatically reshaping itself in an endless, slow-motion movement
  5. 9. what is the method of heat transfer called?
  6. 10. What is plate tectonics?
  7. 11. These currents cause the movement of the tectonic plates that make up the Earth's crust
  8. 12. Top solid layer of mantle
Down
  1. 2. Under solid part
  2. 3. "Pangea is called this today"
  3. 5. Boundary Where new crust is generated as the plates pull away or separate from each other
  4. 7. proposed at one time the continents were joined together once and moved slowly to current locations
  5. 8. What natural disaster does the movement of tectonic plates cause?
  6. 9. Boundary where crust comes together
  7. 13. Force where smaller convection currents near the subducting crust
