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