Across
  1. 4. molten rock that is underground
  2. 6. energy that comes from a source and travels through space at the speed of light
  3. 8. long chain of oceanic islands with intense volcanic and seismic activity and orogenic processes
  4. 10. the geologically altered remains of a once-living organism and/or its behaviour
  5. 13. current, heat transfer involving the movement of energy and heat from one place to another
  6. 14. the movement of continents resulting from the motion of tectonic plates
  7. 15. when two plates come together
  8. 16. a lowland region that forms where Earth's tectonic plates move apart
  9. 18. a fracture or zone of fractures between two blocks of rock
  10. 20. heat is transferred by movement of a heated fluid such as air or water
  11. 21. large slabs of rock that divide Earth's crust
Down
  1. 1. a supercontinent that incorporated almost all the landmasses on Earth
  2. 2. a path along the Pacific Ocean with active volcanoes and frequent earthquakes
  3. 3. magma emerging as a liquid onto Earth's surface
  4. 5. heat energy is transmitted through collisions between atoms or molecules
  5. 7. places where plates slide sideways past each other
  6. 9. plate tectonics of the edge of one crustal plate descending below the edge of another
  7. 11. a scientific theorymajor landforms are created as a result of Earth's subterranean movements
  8. 12. an opening in the Earth's crust through which lava ash and gases erupt
  9. 17. a small area with a relatively hot temperature in comparison to its surroundings
