Tectonic plates

3. The layer of hot, solid material between the crust and core.
5. The rigid outer layer of the Earth, consisting of the crust and upper mantle.
6. The vertical elevation of the Earth's surface
10. Movement in the mantle caused by heat differences, driving plate movement
11. The point on the surface directly above an earthquake's origin.
12. Molten or semi-molten rock beneath the surface.
13. A vent in the crust where magma and gases erupt.
16. Massive, rigid, moving pieces of the Earth's lithosphere.
18. zones cold oceanic lithosphere sinks back into the mantle and is recycled
19. A volcanically active area far from a plate boundary.
21. The process where one tectonic plate sinks beneath another.
23. Where two plates move away from each other.
24. Vibrations caused by sudden movement of rock along a fault.

1. Hypothesis that continents move slowly across the Earth's surface.
2. Process forming new oceanic crust at mid-ocean ridges.
4. Where two plates move toward each other.
7. tectonics the understanding that the top layer or lithosphere of the Earth's crust is divided into many large rocky plates
8. Boundary Where two plates slide past each other horizontally.
9. The ancient supercontinent that included all of Earth's landmasses
14. The outermost layer of the Earth.
15. The soft, plastic layer in the upper mantle that the plates move on.
16. Triggered by large, underwater earthquakes or volcanic eruptions.
17. An underwater mountain chain formed by divergent plates.
20. A deep valley formed where two plates move apart.
22. A break in Earth's crust along which movement occurs.
