  1. 2. Scientists study these in order to learn about the interior of the earth.
  2. 7. These are formed under water at divergent plate boundaries. They are areas where new ocean crust is formed.
  3. 8. Layer of earth that is composed of Fe & Ni and is solid.
  4. 10. Theory that the continents were once as one large, single land mass.
  5. 14. These form under water (on the ocean floor) at most convergent boundaries.
  6. 17. This is a type of heat transfer (hint: lava lamp). Some scientist believe these are occurring in the mantle and moving the tectonic plates.
  7. 18. Earths thickest layer.
  8. 19. This forms on land at divergent plate boundaries. There is a great one in Eastern Africa.
  9. 21. Type of plate boundary where two plates collide.
  10. 23. Type of plate boundary where two plates slide past each other in opposite directions.
  11. 24. Scientist that proposed Earth's continents were once joined together in one single land mass

  1. 1. These occur at transform boundary faults and can cause tremendous devastation.
  2. 2. When one tectonic plate moves underneath another one, it's called this.
  3. 3. The name of the supercontinent that existed 245 million years ago.
  4. 4. Word used to describe the state of the mantle.
  5. 5. Type of plate boundary where two plates separate or move apart.
  6. 6. The cool, outermost layer of Earth that consists of the crust and uppermost part of the mantle.
  7. 9. Type of crust that is thinner and contains basalt.
  8. 11. The bending and crumpling of rock. This happens at continental vs. continental convergent boundaries and results in the tallest mountains.
  9. 12. The process of plates sliding past each other in opposite directions. This can be found at transform boundaries and results in faults.
  10. 13. The layer just below the lithosphere.
  11. 15. Layer of earth with the lowest temperature.
  12. 16. This is the process of creating new oceanic crust.
  13. 17. Type of crust that is thick and contains granite.
  14. 20. Areas along the transform boundary created by the shearing of two pieces of crust. There is a famous one in California.
  15. 22. Layer of earth that is composed of Fe & Ni and is liquid.
