PLATE TECTONICS
Across
- 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.
Down
- 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.
