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
strike-slip fault the rocks on either side of the fault slip past each other sideways, with little up or down motion
plateau a large area of flat land elevated high above sea level
earthquake the shaking and trembling that results from movement of rock beneath Earth's surface
focus the area beneath Earth's surface where rock that was under stress begins to break or move
epicenter the point on the surface directly above the focus
P wave seismic waves that compress and expand the ground like an accordion
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
seismogram the pattern of lines that is record an earthquake's seismic waves produced by a seismograph
