Plate Tectonics

2. Melted rock above the Earth's surface
6. When one plate goes under another one
8. The hottest of Earth's layers; also the innermost layer of Earth
9. The process of plates moving around the Earth
11. The thickest layer of the earth; where convection currents cause plates to move
13. Two plates moving past each other
16. A phenomenon that occurs anytime two plates get stuck and then suddenly unstuck

1. Two plates that are coming together
3. The layer of Earth that makes up most of the tectonic plates
4. Two plates that are moving apart
5. An elevated part of Earth's crust with no magma inside; formed by two plates of equal density coming together
7. An extra-hot part of the mantle where volcanoes like Hawaii and Yellowstone have formed
10. A deep part of the ocean formed when one plate goes under another one
12. An area where magma comes up to the Earth's surface
14. An area of the ocean with several bumps formed by the spreading of two plates away from each other
15. Melted rock beneath the Earth's surface
