Down: 1) waves generated by an earthquake2) measure of the energy released during an earthquake3) cause rock particles to move back and forth in the same direction the wave is traveling5) break in rock caused by shear forces, where rocks move past each other without much vertical movement; In other words, rocks on either side the fault are moving past each other without much upward or down word moment9) occurs when wet soil acts more like a liquid during an earthquake wet In other words, soil can be strong most of the time but the shaking of an earthquake can cause it to act like a liquid.10) in an earthquake, the point below Earth’s surface where energy is released in seismic waves; the point where this energy release first occurs11) instrument used to measure earthquake waves and record the time that each arrived12) Surface along which rocks move when they pass their elastic limit and break; In other words, once the elastic limit is passed the rocks my break when rock break they move along this surface Across: 4) seismic sea wave that begins over an earthquake focus and can be highly destructive when it crashes on shore; in other words, ocean waves caused by an earthquake5) move through earth by causing rock particles to move at right angles to the direction of the wave6) break in rock caused by compressive forces, where rock above the fault surface moves upward relative to the rock below the fault surface In other words, they result from compression forces that squeeze rock. If rock breaks from forces pushing from opposite directions, rock above this fault surface is forced up and over rock below the fault surface.7) Vibrations produced by the breaking of rocks along a fault; plates (rocks) slide past one another to cause this8) the point on earth surface directly above the earthquake focus13) move rocks particles in a backward rolling motion and a side-to-side, swaying motion14) break in rock caused by tension force where rock above the fault surface moves down relative to the rock below the fault surface
