Across
  1. 2. Magma gets pushed out and diverges and gets denser as it goes and pushes the ocean floor with it
  2. 6. Oceanic plates diverge and make a valley
  3. 11. the heating of an object through rays
  4. 12. The heating of an object through touch
  5. 15. An belt in the Atlantic Ocean that volcanoes form around
  6. 17. Underwater mountain ranges
  7. 18. Pieces of the crust that get moved by convection currents
  8. 19. The theory that plates are moved and create continents
  9. 20. Boundary A boundary that moves past each other
  10. 21. The heating of an object through liquid
Down
  1. 1. Materials on the ocean floor like pillow lava, and drill samples
  2. 3. boundary A boundary that moves towards each other
  3. 4. The oceanic plates get sucked down by gravity because it is too dense
  4. 5. An underwater canyon
  5. 7. Pieces of the ocean floor that are magnetic and get sucked towards the deep ocean trench
  6. 8. boundary A boundary that moves away from one another
  7. 9. How much mass or volume is in an object
  8. 10. The super continent that existed millions of years ago
  9. 13. The idea that plates slowly move over time
  10. 14. Traces of organic materials preserved inside rocks
  11. 16. cracks in the Earth's crust
