Chapter 6 Vocabulary

Stress: a force that acts on rock to change its shape or form
Tension: stress that stretches a rock a rock so that it becomes thinner in the middle
Compression: stress that squeezes rock until it folds or breaks
Shearing: stress that pushes masses of rock in opposite directions, in sideways movement
NormalFaults: a type of faults where the hanging wall is slides downward; caused by tension in the crust
HangingWall: the block of rock that forms the upper half of the fault
FootWall: the block of rock that forms the lower half of a fault
ReverseFaults: a type of fault where the hanging wall slides upward; caused by compression in the crust
StrikeslipFault: a stripe of fault where rocks on either side move past each other sideways with a little up-or-down motion
Anticline: an upward fold in rock formed by compression of Earth's crust
Sydcline: a downward fold in rock formed by compression of Earth's crust
Plateau: a landform that has a high elevation and a more or less level surface
Earthquake: the shaking that results from the movement of rock beneath the surface
Focus: the point beneath Earth's surface where rock breaks under stress and causes an earthquake
Epicenter: the point on Earth's surface directly above an earthquakes surface
PWaves: a type of seismic wave that compresses and expands the ground
SWaves: a type of seismic wave that moves the ground up and down or side to side
SurfaceWaves: a type of seismic wave that forms when P waves and S waves reach Earth's surface
MercalliScale: a scale that rates earthquakes according to their intensity and how much damage they cause at a particular
Magnitude: the measurement of an earthquake's strength based on seismic waves and movement along faults
RichterScale: a scale that rates an earthquake's magnitude based on the size of its seismic waves
Seismograph: a device that records ground movements caused by seismic waves as they move through Earth
MomentMagnitudeScale: a scale that rates earthquakes by estimating the total energy released by an earthquake
Friction: the force that opposes the motion of one surfaces as it moves across another surface
Seismogram: the record of an earthquake’s seismic waves produced by a seismograph
Liquefaction: occurs when an earthquake’s violent shaking suddenly turns loose, soft soil and into liquid mud
AfterShock: an earthquake that occurs after as larger earthquake in the same area
Tsunami: a giant wave usually caused by an earthquake beneath the ocean floor
Baseisolatedbuilding: a building mounted on bearings designed to absorb the energy of an earthquake
