Across
- 5. This word means "rocky globe" and is the part that is composed mostly of rock. It includes the crust and the outer mantle.
- 7. Very large pieces of land that move due to convection currents in the mantle.
- 11. An area where two plates move towards each other.
- 12. The soft but mobile layer of rock found below the lithosphere. AKA lower mantle.
- 13. An area where two plates move AWAY from each other, causing seafloor spreading and new land to be made.
- 14. Cycles of hot molten rock in the mantle that rise to nearer the surface, cool, and then sink back to the much warmer core of earth.
- 16. Scientist who first stated the theory of continental drift and plate tectonics.
- 18. This term refers to an area around the Pacific Plate that is particularly abundant in volcanoes, earthquakes, and mountain ranges.
- 19. The major boundary that runs up and down California.
Down
- 1. A type of convergent boundary where one plate sinks underneath a different plate.
- 2. This is by far the largest portion of Earth lying between the Earth's crust and core.
- 3. A natural and renewable energy resource that is produced by Earth's naturally occurring heat, steam, and hot water.
- 4. The liquid layer surrounding the inner core, this layer is made up of iron and nickel.
- 6. This is an underwater crust phenomenon that occurs at divergent plate boundaries.
- 8. The outermost layer of the Earth made up of the lithosphere and asthenosphere together.
- 9. A structure of the crust that forms at a divergent boundary.
- 10. The most center part of the planet that is solid and made mostly of iron.
- 15. An area where two plates meet, but instead of colliding together or spreading apart, the plates slip past each other, edge against edge. A good example of this is the San Andreas Fault is a good example of this.
- 17. The supercontinent that existed at the end of the Paleozoic Era consisted of all land masses and continents joined together.
