- What makes an earthquake?
- How does the seismometer shown in the video work?
- What would the marker line look like if there were no Earth movements underneath the box?
- The seismometer the ZOOM cast members made measures earthquake (seismic) waves that move sideways, or parallel to the Earth's surface. When the cast members bounced the table up and down by hitting it, the seismometer just bounced up and down and didn't make the big curves it made when they moved the box back and forth. How could you construct a seismometer that would show the size of up-and-down seismic waves?
- Find out how a real seismometer works. In what ways is the ZOOM seismometer a realistic model?
