the friction of plates sliding past one another at transform boundaries can cause

elastic rebound theory
rocks are held/locked in place by friction on either side of a fault, when deformation exceeds frictional force holding rocks together, a sudden slip occurs along the fault
states that when the stress in rocks becomes so great, they fracture, separate, and spring back to their original state
occur when rock under stress suddenly shifts along a fault
forces that can change the size and shape of rocks
hypocenter refers to

epicenter
fault line
seismic wave

epicenter
fault
hypocenter
focus
the point on Earth's surface directly above an earthquake's focus (starting point)
focus
hypocenter
epicenter
fault

(a) -focus earthquakes cause more damage due to the energy present at the surface
p-waves
compression waves; fastest waves, particles move back and forth in the direction of the wave and are the first recorded waves on the seismograph -- these waves can travel through all 3 states of matter
second recorded waves on seismograph; can only travel through solid material; these waves move in a side-to-side direction perpendicular to the direction of the wave
slowest moving waves; waves are destructive when traveling through loose earth, due to the rising and falling of the crust
surface waves
compression waves; fastest waves, particles move back and forth in the direction of the wave and are the first recorded waves on the seismograph -- these waves can travel through all 3 states of matter
second recorded waves on seismograph; can only travel through solid material; these waves move in a side-to-side direction perpendicular to the direction of the wave
