Plate Tectonics

2. The process of continents breaking up, subsiding and allowing in the sea
5. a place where extremely hot material from inside the earth erupts to the surface
7. Crust- Crust that forms the continents
8. Wave- the shaking, eave like movement of the ground in an earthquake
9. where plates are sliding parallel to each other but in opposite directions
12. molten rock that has erupted onto the earth's surface
13. The process of crust spreading apart.

1. Crust- Crust that is found on the ocean floor
2. an instrument that detects seismic waves from an earthquake
3. The point on the earth's surface directly above the focus
4. Tectonics- the theory that the earth's crust is cracked into many large pieces that move across the asthenosphere
6. Trench- A deep trench in the ocean floor that is much deeper than the rest of the ocean floor
8. Spreading- The process of new crust being formed at ocean ridges, and spreading out
10. a huge wave in the ocean caused by an earthquake on the seafloor
11. molten rock below the earths surface
