- 2. motion occurs when 2 plates pull away from each other
- 3. an instrument that records vibrations in the ground
- 4. gap an area along a fault where relatively few earthquakes occurred recently but where strong earthquakes have occurred in the past
- 7. the point on Earth's surface directly above an earthquake's starting point
- 9. hypothesis a hypothesis taht is baszed on the idea that a major earthquake is more that likely to occur along the part of an active fault where no earthquakes have occured for a certain period of time
- 10. wave a seismic wave that causes particles of rock to move in a side to side direction
- 12. a tracing of earthquake motion that is created by a seismograph
- 13. motion occurs when 2 plates push together
Down
