Down
  1. 1. The process in Earth’s mantle that scientists believe is driving the movement of the plates due to the heating and cooling of magma.
  2. 2. A lowland region that forms where two of Earth's continental tectonic plates move apart or separate
  3. 4. The broken sections of Earth’s crust; they constantly move around on Earth’s mantle
  4. 5. The process that occurs when one plate sinks beneath another plate because it is more dense
  5. 6. The supercontinent that included all current land masses before they split apart
  6. 8. A curved chain of volcanic islands
  7. 11. A theory stating that all of the continents on Earth used to be joined as one giant landmass and have since slowly drifted to their current locations
