| A | B |
|---|
| Fault | Surface of earth where rock breaks and move |
| Elastic Limit | Passing the elastic limit |
| Elastic Rebound Theory | Locked faul ts realeased when the fault releases energy |
| Normal Fault | pull apart fracture in rocks |
| Tension | Normal Fault |
| Reverse Faults | compression fracture in rocks |
| Strike slip faults | not much upward&downward movement |
| Sheering forces | creates transform faults |
| Tectonic Plates | boundaries which most earthquakes occur |
| Convergent Plates | where plates collide, and one sinks beneath the other |
| Divergent Boundaries | Where plates seperate and move in opposite directions |
| Primary Wave | fastest waves |
| Secondary waves | secondary seimic waves that travel slower |
| surface waves | seismic wave that follows the earths surface |
| Seismograph | records the seismic waves from EQ |
| Seismic waves | Intense vibrations that travel outward from the focus |
