Across
  1. 3. / Amount of force pushing on a surface or area.
  2. 7. Transfer / the movement of energy from a warmer object to a cooler object
  3. 8. core / solid part of the core
  4. 9. / the layer of hot, solid material between Earth's crust and core.
  5. 10. Drift / hypothesis that the continents slowly move across Earth's surface
  6. 13. / soft layer of the mantle which the lithosphere floats on.
  7. 15. core / this part is the molten part of the Earth's core.
  8. 16. Tectonics / the theory that pieces of Earth's lithosphere are in constant motion driven by convection currents in the mantle
  9. 18. / a plate boundary where two plates move away from each other
  10. 19. / the layer of rock that forms Earth's outer surface
Down
  1. 1. / a system that determines the distance of an object underwater by recording echoes of soundwaves
  2. 2. / transfer of heat by movements of a fluid
  3. 4. / direct transfer of energy through empty space through electromagnetic waves
  4. 5. / the process by which oceanic crust sinks beneath a deep ocean trench and back into mantle
  5. 6. / a plate boundary where two plates move toward each other
  6. 11. / a plate boundary where two plates move past each other in opposite directions
  7. 12. / a rigid layer made up of the uppermost part of the mantle and the crust
  8. 14. / name of the single landmass that broke apart 225 million years ago
  9. 16. / a section of a lithosphere that slowly moves over the asthenosphere carrying pieces of continental and oceanic crust
  10. 17. waves / A vibration that travels through Earth carrying the energy released during an earthquake.
