Explanation:

These are fill-in-the-blank and multiple-choice questions focused on basic earthquake and earth science concepts, with answers based on standard geology knowledge.

Answer:

1. thousands
2. tectonic plates
3. inflexible
4. tectonic
5. fault
6. mountains
7. seismograph
8. Magma
9. more
10. potential
11. 3
12. epicenter
13. Search and rescue dogs (or heavy machinery)
14. compare
15. 32

A- (Example: Most earthquakes originate from tectonic plate movement, not random crust shifts)
B- (Example: The Richter Scale is logarithmic, so each magnitude increase is 32x stronger)
C- (Example: Seismographs use seismic waves to pinpoint earthquake locations)
