Across
  1. 3. Molten rock that breaks through the Earth's surface
  2. 4. The thick layer of hot, solid rock between Earth's crust and molten core
  3. 8. A boundary where two tectonic plates move away from each other
  4. 10. A deep valley on the ocean floor where subduction takes place
  5. 14. The rising of regions of Earth's crust to higher elevations
  6. 16. A vent in Earth's crust through which lava, steam, and ash erupt
  7. 17. The transfer of heat by the movement of fluid, driving plate motion
  8. 18. An underwater mountain range formed by plate separation
  9. 19. A boundary where two tectonic plates slide past each other horizontally
Down
  1. 1. Molten rock beneath the Earth's surface
  2. 2. A break or crack in Earth's lithosphere along which rocks move
  3. 5. The rigid outer layer of Earth consisting of the crust and upper mantle
  4. 6. Stress that squeezes rock until it folds or breaks
  5. 7. The plastic-like, flowing layer of the mantle just below the lithosphere
  6. 9. Stress that stretches and pulls rock apart
  7. 11. A long valley formed by the sinking of crust where plates diverge
  8. 12. The thin, rocky, outermost layer of the Earth
  9. 13. The process where a denser tectonic plate sinks beneath a lighter plate
  10. 15. A boundary where two tectonic plates collide or move toward each other
