|
|
Locating the earthquake epicenter by drawing the circles and finding where the three intersect is called |

Earthquakes |
|
|
Earthquake waves that arrive at the surface first |
P-waves |
|
|
Earthquake waves that cause the ground to shake and make rocks roll like an ocean wave |
Surface waves |
|
|
The movement of rock particles during the passage of s waves |
Up, down/side-side |

|
|
Changes in Earth's interior have been detected due to |
Seismic waves |
|
|
The force that squeezes rock together |
Compression |
|
|
When the force on rocks is great enough, they break, producing vibrations called |
Earthquakes |
|
|
Once the elastic limits of rocks is passed, they break and move along surfaces called |
Faults |
|
|
Measuring the time between the arrival of p and s waves determines the distance between the epicenter and the |
Seismograph station |
|
|
Point a where energy is initially released during the earthquake is called the |
Focus |
|
|
Point b is called the earthquake |
Epicenter |
|
|

|
When arrows at plate boundaries ate point towards each other it is a |
Convergent |
|
|
When arrows are pointed away from each other at plate boundaries it is |
Divergent |
