Across
  1. 1. the sinking movement of ocean floor back into the mantle
  2. 6. the layer below the crust, made up of a mix of magma and rock
  3. 11. the process of magma rising out of cracks in the Earth's crust and hardening into new rock at the bottom of the ocean
  4. 12. undersea valleys that are the deepest part of the ocean
  5. 13. an idea that can be tested by investigation or experimentation
  6. 14. rock that comes from smaller rocks and/or living matter being pushed together
  7. 15. The Earth's crust is broken up into this large slabs of rock
Down
  1. 2. these currest in the mantle push the tectonic plates to move around
  2. 3. a super continent that existed at the time of the dinosaurs, was made up of all the current continents combined to form one massive landmass.
  3. 4. rock that comes from other rock being given lots of heat and pressure
  4. 5. the man who came up with the hypothesis of continent drift
  5. 7. the outermost layer of the Earth, mostly solid rock with small amounts of metal and magma
  6. 8. the idea that the continents of the Earth have moved around the world over the course of millions of years
  7. 9. long zipper-like chains of undersea mountains
  8. 10. rock that comes from magma or lava cooling
