Across
  1. 1. Pull – Force caused by a sinking plate pulling the rest of it down.
  2. 6. Boundary – Plate boundary where plates slide past each other.
  3. 7. – The vast ocean that surrounded Pangaea.
  4. 9. Push – Force caused by rising magma at mid-ocean ridges pushing plates apart.
  5. 10. – Rigid outer layer of Earth made of the crust and upper mantle.
  6. 11. Core – The liquid layer of Earth’s core that causes the magnetic field.
  7. 12. Waves – Seismic waves that travel through Earth’s interior.
  8. 14. Force – General term for what causes plate motion.
  9. 16. Waves (S-waves) – Slower seismic waves that only travel through solids.
  10. 17. Boundary – Plate boundary where plates move apart.

Down
  1. 2. – The soft, plastic-like layer of the mantle beneath the lithosphere.
  2. 3. – Ancient supercontinent that existed millions of years ago.
  3. 4. – Thick layer of rock between the crust and the core.
  4. 5. – The Earth's outermost solid layer.
  5. 7. Waves (P-waves) – Fastest seismic waves that move through solids and liquids.
  6. 8. (Moho) – Boundary between the crust and mantle.
  7. 13. Suction – Force created as a subducting plate drags mantle material.
  8. 15. Convection – Heat-driven circulation in the mantle that moves plates.
  9. 18. Core – The solid innermost part of the Earth’s core.
