  3. 11. A hot, solid center made of iron and nickel under high pressure.
  4. 12. The outermost layer of Earth where humans live, made of solid rock.
  5. 14. Rising and sinking rock movement that drives plate motion.
  6. 15. A molten metal layer that helps generate Earth's magnetic field.
  7. 18. Thinner, denser crust under oceans, mostly basalt.
  8. 19. Plates sliding past each other, often causing earthquakes.
  9. 20. An invisible shield around Earth that blocks solar radiation.
Down
  1. 1. Giant moving slabs of crust and upper mantle.
  2. 3. Plates crashing together, creating mountains or trenches.
  3. 4. Earthquake vibrations that help reveal Earth’s inner structure.
  4. 5. Process that creates Earth's magnetic field using outer core motion.
  5. 6. The thick layer beneath the crust that flows slowly over time.
  6. 7. A dark, iron-rich rock found in oceanic crust.
  7. 9. A sudden ground shaking from plate movement or stress release.
  8. 10. A light-colored rock high in silica, found in continental crust.
  9. 13. The deepest part of Earth, made of metal and split into two layers.
  10. 16. Thicker part of the crust under continents, mostly granite.
  11. 17. Plates moving apart, forming new crust at ridges.
