Across
- 4. Many volcanoes in a chain together (such as Mount Fuji)
- 5. The shaking of Earths surface due to a sudden release of energy in the Earth's lithosphere that creates seismic waves
- 9. When heated mantle material is rising from deep inside the mantle, while cooler mantle material sinks, creating a convection current throughout the Mantle
- 10. Hot material beneath Earth's Crust that forms magma or other rock materials when cool
- 11. Where pieces of Earths crust diverges on land (a deep valley)
- 12. the idea that continents slowly move over Earth's surface
- 13. Tectonic Plates that slip past each other
- 15. The thickest layer of the Earth that contains convection currents
- 16. Breaks in Earth's crust where rocks have slip past each other
- 17. The process in which a mid ocean ridge continually adds new material to the ocean floor
- 18. Theory in which Earth's plates are in slow constant motion, driven by convection currents in Earth's mantle
- 19. the process in which old ocean floor falls into a deep ocean trench back into the mantle (Turning back into magma)
Down
- 1. a trace of an ancient organism that has been preserved in rock
- 2. The material at the bottom of the ocean
- 3. Tectonic plates that move apart from each other
- 6. Tectonic Plates that come together
- 7. a supercontinent that existed about 300 million years ago
- 8. deep underwater canyon in which old sea floor falls into during subduction
- 14. Pieces of Earth's crust
- 15. a formed mountain range that runs along the middle of some ocean floors (Looks like seams)
