2. mountains formed when blocks of Earth's crust are pushed up by forces inside Earth
4. A tall, cone-shaped volcano in which layers of lava alternate with layers of ash and other volcanic materials
5. A mountain formed by blocks of rock uplifted from normal faults. (Include hyphen)
7. A scale that rates an earthquake's magnitude based on the size of its seismic waves.
13. Move through rack material by causing particles in the rock to vibrate at right angles (up and down) to the direction in which the waves are moving; slower than primary waves
14. A scale that rates earthquakes by estimating the total energy released by an earthquake (No Space)
16. Shaking that results from the movement of rock below the surface
17. the area covered by lava as it pours out of a volcano's vent (No space)
19. The area on the surface directly above the focus
20. Using the distance from three stations to determine the epicenter of an earthquake
23. Vibrations that travel through Earth carrying energy released by earthquake (no space)
24. a wide, gently sloping volcano made of layers of lava and formed by quiet eruptions
28. Type of fault where rocks move sideways past one another (include hyphen)
29. A scientist who studies earthquakes

1. Breaks in Earth's crust where rocks slip past one another
3. the flow of ash, cinders, bombs, and gases down the side of a volcano during an explosive eruption
6. This type of fault occurs when the rocks move towards one another, with one sliding above the other
8. The central point of the earthquake beneath Earth's crust
9. a scale that rates the amount of shaking from an earthquake (No space)
10. seismic waves that travel along the Earth's surface in a circular motion
11. Instrument used to measure horizontal or vertical motion during an earthquake.
12. A small, steeply sloped volcano that forms from moderately explosive eruptions of pyroclastic material. (No space)
15. mountain that forms when magma is forced upward and flows onto Earth's surface
18. A mountain that forms as continental crust is compressed and rocks bend into large folds
21. This type of fault occurs when the rocks move away from one another, one moving up and one down
22. The digital line graph that shows intensity of an Earthquake's energy
25. movement of saturated, slippery soil downhill under the influence of gravity
26. a cloud of ash that forms in the air after some volcanic eruptions (No space)
27. Travel the fastest through rock material by causing particles in the rock to move back and forth , or vibrate, in the same direction as the waves are moving.
