Across
  1. 5. Visible cracks within the Earth’s surface where two tectonic plates meet
  2. 7. These are the spot where two tectonic plates meet
  3. 8. This theory states that magma rising at the mid-ocean ridge pushes crust away
  4. 10. This theory states that the crust is broken up into pieces known as tectonic plates
  5. 12. The idea that the continents once moved on mantle and move today
  6. 13. This plate boundary has the plates moving AWAY from one another
  7. 16. This is movement of magma due to warmer, less dense magma rising while cooler, more dense magma sinks
  8. 18. The most famous supercontinent
  9. 19. Last name of scientist who proposed seafloor spreading
  10. 21. This was a specific fossilized animal found on South America and Africa
  11. 22. This mountain range formed when The pacific plate slides below below the South American
  12. 23. This is the process of magma rising at the mid-ocean ridge
  13. 24. This plate boundary has the plates SLIDING AGAINST/PAST one another
Down
  1. 1. This occurs when the heavier, more dense oceanic crust slides below the continental crust
  2. 2. This mountain range formed when the Indian and Eurasian plates collided
  3. 3. These remains of organisms were one piece of evidence used to support continental drift
  4. 4. These form on land at a divergent boundary (There is one in Africa)
  5. 6. Last name of scientist who proposed theory of continental drift
  6. 9. These are vibrations in the ground as a result of tectonic plates brushing against one another
  7. 11. Specific region where an oceanic plate slides below the continental, often creating a trench
  8. 14. Openings within the Earth where magma rises
  9. 15. This plate boundary has the plates moving TOWARDS one another
  10. 17. This region within the Pacific with the highest concentration of volcanoes
  11. 20. The most famous fault line found in California
