Plate Tectonics

5. A plate where extremely hot material from inside the earth erupts at the surface
7. The point of the earths surface directly above the focus of an earthquake
8. The crust that forms in the continent
9. Tectonic plates causing the earth to have rapid movement of the ground, usually back and fourth and up and down in a wave motion
10. The theory that the earths crust is cracked into large pieces that move
14. Molten rock below the earths surface
15. spreading The process of new crust forming at the ocean ridges and spreading outwards
16. The process of continents breaking up, subsiding and allowing in the sea

1. The crust that forms the ocean floor
2. Where the crust is sinking down into the earth
3. An instrument that detects the seismic waves from an earthquake
4. A huge wave in the ocean caused by an earthquake on the seafloor
6. The separation of continents drifting across the ocean
11. A deep trench in the ocean floor that is deeper than the rest of the ocean floor
12. The shaking, wave-like movement of the ground in an earthquake
13. Molten rock that has erupted onto the earths surface
