Science

2. Form when compression during plate collision folds and lifts rock layers
3. Larger waves on a seismogram show greater recorded ground motion
5. Pulls rock apart
6. The point on Earth’s surface directly above the focus
9. Relatively flat land
10. The slowest waves that do a rolling,up-and-down, and side-to-side movement
11. where two plates meet
13. bottom part of a fault
14. strike-slip fault
16. Stress builds as rock bends and changes shape
17. Pushes rock in opposite directions
22. A larger gap between the p-wave and s-wave arrivals means the epicenter is farther from the station and a smaller means it’s closer
25. Based on observations rather than an instrument, intensity can differ from place to place
28. Earthquake maps show that most earthquakes occur near
29. The instrument that detects and records seismic waves
30. each increase of 1 whole magnitude releases about 32 times as much energy

1. form as tension creates normal faults and blocks move vertically
4. magnitude describing the earthquake’s size intensity describes the effect at a particular place
7. Magnitude related to the total energy released using seismic data
8. Frequent earthquakes and volcanoes around the Pacific Ocean associated with plate boundaries
12. top part of fault
15. Magnitude based on the size of seismic waves recorded by a seismograph
18. a downward fold in rock like a v
19. An object resists a change in it’s motion
20. The second fastest waves that arrive second and do a side-to-side motion
21. Vibrations that carry the energy released by an earthquake outward from it’s source
23. an upward fold in rock like an arch
24. The record of earthquake waves produced by a seismograph
26. The point inside earth where an earthquake begins
27. Squeezes rock together
28. The fastest waves that arrive first and are push-pull or compressional motion
