- 2. An instrument used to detect and record earthquakes
- 4. the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.
- 5. A 1 -10 scale that measures of the strength of earthquakes
- 8. the place where the rupture of the plate boundary that led to the earthquake first happened.
- 9. _____ plates are pieces of Earth's crust and uppermost mantle, together referred to as the lithosphere.
Down
- 1. A _____ boundary occurs when two tectonic plates move away from each other.
- 3. A number, used on the Richter Scale, to quantify the amount of seismic energy released by an earthquake
- 6. the point on the surface of the Earth directly above the hypocenter of an earthquake.
- 7. waves of energy that travel through Earth's layers, and are a result of earthquakes, volcanic eruptions, magma movement, etc.
