Across
  1. 3. The process of plates sliding past each other in opposite directions. This can be found at transform boundaries and results in faults
  2. 6. The word used to describe the state of the mantle
  3. 7. The cool, outermost layer of the Earth that consists of the crust and uppermost part of the mantle
  4. 9. Type of plate boundary where two plates collide
  5. 11. The layer just below the lithosphere
  6. 12. Layer of Earth that is composed of Fe & Ni and is liquid
  7. 13. Scientist that proposed Earth's continents were once joined together as a single land mass
  8. 16. This is a type of heat transfer (hint: lava lamp). Some scientists believe these are occurring in the mantle and moving the tectonics plates
  9. 19. These are formed under water at divergent plate boundaries. They are areas where new crust is formed
  10. 21. Areas along a transform boundary created by the shearing of two pieces of crust. There is a famous one in California
  11. 22. These form under water (on the ocean floor) at most convergent boundaries
  12. 23. Earth's thickest layer
  13. 25. Scientists study these in order to learn about the interior of the Earth
  14. 26. Layer of Earth with the lowest temperature
  15. 27. Type of crust that is thinner and contains basalt
Down
  1. 1. Layer of Earth that is composed of Fe & Ni and is solid
  2. 2. Type of crust that is thick and contains granite
  3. 4. This is the process of creating new oceanic crust
  4. 5. Theory that the lithosphere is divided into tectonic plates that move on the asthenosphere
  5. 8. This forms on land at divergent plate boundaries. There is a great one in eastern Africa
  6. 10. Type of plate boundary where two plates separate or move apart
  7. 14. The name of the supercontinent that existed 245 million years ago
  8. 15. The bending and crumpling of rock. This happens at continental vs continental convergent boundaries and results in the tallest mountains
  9. 17. Theory that they continents were once joined as one large, single land mass
  10. 18. When one tectonic plate moves underneath another one, it's called this
  11. 20. These occur at transform boundary faults and can cause tremendous devastation
  12. 24. Type of plate boundary where two plates slide past each other in opposite directions
