Earthquakes
Across
- 4. - Large ocean wave caused by an underwater earthquake.
- 7. - Plate boundary - Plates slide past each other.
- 9. - Plates - Large pieces of the Earth's crust that move.
- 13. - Instrument that records earthquake waves.
- 14. - Process where one tectonic plate moves beneath another.
- 15. - Crack in the Earth's crust where earthquakes originate.
- 16. - Area directly above the earthquake's origin.
- 18. - Measure of the energy released by an earthquake.
Down
- 1. - Primary seismic wave that compresses and expands particles.
- 2. - Tectonics - A rigid segment of the Earth's lithosphere.
- 3. - Measure of the earthquake's effects at specific locations.
- 5. - Study of earthquakes and seismic waves.
- 6. - Saturated soil temporarily loses strength during an earthquake.
- 8. - Related to earthquakes or other vibrations of the Earth.
- 10. - Small earthquakes that precede a larger one.
- 11. - Smaller earthquake that follows the main shock.
- 12. - Scale used to quantify earthquake magnitude.
