2. the supercontinent that formed 300 million years ago and that began to break up 200 million years ago
3. the solid, outer layer of Earth that consists of the crust ad the rigid upper part of the mantle.
4. stress that occurs when forces act to stretch an object
7. a movement or trembling of the ground.
8. a break in a body of rock along which one block moves relative to another.
13. the bending, tilting, and breaking of earth's crust

16. the location within Earth along a fault at which the first motion of an earthquake occurs
17. the thin and solid outermost late of Earth above the mantle.

1. the bending of rock layers due to stress
2. the theory that Earth's outer layer is made up of large, moving pieces.
3. magma that flows onto Earth's surface
5. stress that occurs when forces act in parallel but opposite directions
6. a vent or fissure in Earth's surface through which magma and gases are expelled.
9. the strong, lower part of the mantle between the asthenosphere and the outer core.
10. the central part of Earth below the mantle
11. an opening at eh surface of the earth through which volcanic material passes
12. the point on Earth's surface directly above an earthquake's starting point
14. the molten or partially molten rock material containing trapped gases produced under the Earth's surface
