| Question | Answer |
|---|---|
| An earthquake is caused by plate movement when the crust breaking along a | fault |
| Rocks break when they reach their | elastic limit |
| The earthquake begins at the | focus |
| The point on Earth's surface directly above the focus is the | epicenter |
| ___ seismic waves travel the fastest. | primary |
| ___ seismic waves reach the seismic station second. | secondary |
| The least number of seismic stations needed to determine the epicenter is | three |
| We can use distances from 3 seismic stations to analyze an earthquake. Where the 3 circles intersect is the | epicenter |
| The area on Earth where no seismic waves are detected is the | shadow zone |
| These waves cannot travel through the liquid outer core | S-waves |
| Both P and S waves slow down when they reach the | asthenosphere |
| P and S waves speed up when they reach the | solid lower mantle |
| The boundary between the crust and the mantle is the | Moho discontinuity |
| Tsunamis often occur at | subduction zones |
| At transform fault boundaries you find ___ faults. | strike-slip |
