    • Question
    • Answer
    • Side 3
    • magnitude
    • The measurement of an earthquakes strength based on seismic waves and movement along faults
    • Fold
    • A bend in rock froms where part of Earth's crust is compressed
    • earthquate
    • The shaking that results from the movement of rock beneath Earth's surface
    • Anticline
    • An upward fold in rock formed by compressionof Earth's crust
    • Hanging wall
    • The block of rock that forms the upper half of a fault
    • footwall
    • The block of rock that forms the lower half of a fault
    • Seismograph
    • A device that records ground movements caused by seismic waves as they move through Earth.
    • Tusunami
    • A giant wave caused by an earthquake on the ocean floor
    • Syncline
    • A downward fold in rock formed by compressionin Earth's crust
    • Base-isolated building
    • A building mounted on bearings designed to absorb the energy of an earthquake
    • Fault
    • A break in Earth's crust where slabs of rock slip past each other
    • Stress
    • A forcethat acts on rock to change its shape or volume
    • Epicenter

    • the point on earth's surface directly abouve an earthquake focus.


    • Strike-slip fault



    • A type of fault where rocks on either side move past each other sideways with little up-or down motion
    • Aftershock
    • An earthquake that occurs after a laarger earthquake in the same area
    • Liquefaction
    • The process by which an earthquakes violent movement suddenly turns loose soil into liquid mud
    • deformation
    • A change in the volume or shape of Earth's crust
    • Shearing


      Tension
    • Stess that pushes a mass of rock inopposite directions

      Stess that sretches rock so that it becomes thinner in the middle.
    • Focus
    • The point beneath Earth's surface whee rock breaks under stress and causes an earthquake.
    • Fault Block mountain
    • A mountain that forms wher a normal fault uplifts a block of rock
    • Normal Fault
    • A type of fault where the hanging wall slides downard: caused by tension in the frust
