| stress | a force that acts on rock to change its shape or volume
🗑
|
||||
| tension | the stress force that pulls on the crust and thins rock in the middle
🗑
|
||||
| compression | the stress force that squeeze rock until it folds or breaks
🗑
|
||||
| shearing | stress that pushes a mass of rock in two opposite directions
🗑
|
||||
| normal fault | the fault cuts through rock at an angle, so one block
🗑
|
||||
| reverse fault | same structure as a normal fault, but the blocks move in opposite directions
🗑
|

🗑
|
||||
| S wave | seismic waves that can vibrate form side to side or up and down
🗑
|
||||
| suface wave | slower than P and S waves, but they can produce severe ground movements
🗑
|
||||
| seismograph | an instrument that records and measures an earthquake's seismic waves
🗑
|
||||
| Modified Mercalli scale | rates the amount of shaking from an earthquake
🗑
|

| magnitude | a single number that geologists assign to an earthquake based on the earthquake's size
🗑
|
||||
| Richter scale | the earliest magnitude scale
🗑
|
||||
| moment magniude scale | rate the total energy an earthquake releases
🗑
