Plate Tectonics
Across
- 1. a vent in a planet's crust from which molten or hot rock and steam come out
- 4. the solid outer surface of the Earth
- 7. the crustal plate located beneath the ocean
- 10. the process of crustal plate movement
- 11. plates in the Earth's crust that hold the continents
- 14. melted rock that rises from the mantle and lies beneath the surface
- 15. points at which the Earth's crust cracks
Down
- 2. the slow process of the Earth's continents moving as the Earth's plates shift
- 3. the ring of volcanoes along the edges of the continents that border the Pacific Ocean
- 5. the large slabs of rock that make up the Earth's crust
- 6. the semi-solid layer of the Earth between the outer and the outer core
- 8. liquid rocck that reaches the surface
- 9. an underwater mountain range that zigzags between all the continents
- 11. the innermost layer of the Earth, made up of a liquid outer core and a solid inner core
- 12. extremely deep areas where two plates meet and one slides under the other
- 13. a single continent made up of all of the Earth's land mass long ago
