Across
- 3. The outer part of the earth, consisting of the crust and upper mantle.
- 8. Waves surface seismic waves that cause horizontal shifting of the Earth during an earthquake
- 9. An opening in the earth’s crust through which molten magma and gases erupt.
- 10. The supercontinent
- 11. boundaries an area on Earth where two or more lithospheric plates collide.
- 12. core The center of the earth
- 14. Group of volcanic islands formed from ocean crust convergence
- 15. ductile region of the upper mantle of Earth.
- 16. Waves are pressure waves that travel faster than other waves
- 17. Convergent Two ocean plates collide and one goes under the other.
- 18. crust Makes up less than 1% of the total volume of the earth.
Down
- 1. Waves A type of seismic body wave in which rock particles vibrate at right angles to the direction of wave travel.
- 2. Spots Not part of a plate boundary but has continual volcanic geothermic activity.
- 3. Plates - regions of Earth's crust and upper mantle that are fractured into plates that move across a deeper plasticine mantle
- 4. Drift The gradual movement of the continents across the earth.
- 5. Tectonics The earth’s crust and upper mantle are broken into sections called plates.
- 6. Zone A complex area which little is known about.
- 7. an area of relatively level high ground.
- 13. Waves type of surface wave that travels near the surface of solids
- 18. Mantle Lies between Earth's dense, super-heated core and its thin outer layer, the crust.
