PLATE TECTONICS

3. A mountain that opens downward to a pool of molten rock below the surface of the earth.
6. This is where two continental plates move apart.
8. The second layer of the Earth. It is the biggest and takes up 84 percent of the Earth.
10. If two continental plates separate, it will form a _______ after millions of years.
12. The layer of the Earth that lies below the lithosphere.
13. The second to last layer of the Earth. It is a magma like liquid layer that surrounds the Inner Core and creates Earth's magnetic field.
15. A geological process that takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced down into the mantle.

1. A continental transform fault that extends roughly 800 miles (1,300 km) through California and it is the deadliest translation.
2. It is a collision of continental and oceanic plate.
4. The rigid outer part of the earth, consisting of the crust and upper mantle.
5. A sudden movement of the earth's crust caused by the release of stress accumulated along geologic faults or by volcanic activity.
7. A method used for locating the epicenter of an earthquake.
9. Two plates slide by one another in opposite directions.
11. The molten rock material under the Earth's crust.
14. The outer layer of the Earth, between the surface and the mantle, which is up to 40 miles deep.
