4. Row 1, Col 1 What are the three types of stress that affects rock? Tension, Compression, Shearing

5. 1,2 Name the three types of waves in order from fastest to slowest P,S, Surface

6. 1,3 Name 5 instruments that can monitor motion along faults Tiltmeter, creepmeter, satellite, laser

7. 1,4 What three words should you remember when a quake occurs Drop, Cover, Hold

8. 2,1 What are the three types of faults that stress can cause? Reverse, Normal, Strike/Slip

9. 2,2 Where exactly does an earthquake occur? Focus

10. 2,3 Which 2 instruments measure horizontal movement Creepmeter, laser-ranging device

11. 2,4 Name 3 things you can do to better secure your home to prepare for a quake Secure chimney, cabinets, foundation move bed away from window

12. 3,1 An upward fold in a rock is called … anticline

13. 3,2 Which type of wave can travel through the outer core of the Earth? Why? P wave-can travel through liquids

14. 3,3 Name two things that a seismograph can record? Seismic waves arrival times /Speed of waves

15. 3,4 Describe what Base-Isolation is and how it works Reduces amount of shaking w/ springs or pads attached to foundation to allow structure to move

16. 4,1 The Himalayas contain many of these kind of faults. Reverse

17. 4,2 Name three things that are only true about surface waves Slowest, largest on seismogram, only travel on surface

18. 4,3 How does a seismograph help us locate the distance to an epicenter. Be specific What information is needed? Arrival times of p and s waves = distance=radius=epicenter(3)

19. 4,4 What happens to wave-length and height of a tsunami when it approaches a land Height increases/wavelength decreases

20. 5,1 What two types of faults move Vertically? Both faults/Normal=tension/Reverse=compression

21. 5,2 Name the three scales that we use to rate earthquake? Which one measures the total energy released during a quake? Magnitude? Intensity? Mercali, Richter, Moment Mag./Moment Mag.

22. 5,3 How far does a P wave travel in 7 minutes? How far does an S waves ravel in 7 minutes? P-4000km / S-1900km

23. 5,4 What type of fault could cause a tsunami to form? Explain Reverse-the ocean floor is thrusted upward moving the water on the ocean floor upward with it
