Layers of Earth, Plate Tectonics and Continental Drift

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.

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.
