Flashcards in earthquakes Deck (23):
earth's outer most layer
movement of the ground caused by the waves of energy releases as move along the faults.
the limit of how far it will stretch or bend.
point on earth's surface directly above the focus.
Surface along which rocks break and move.
Point in earth's interior where the energy releases and occurrs
center of the earth -iron and nickle
measure of the energy reaches in an earthquake.
largest layer, above outer core. -silicon, magnesium, oxygen and iron.
boundary between earth's crust an the mantle -seismic waves travel faster below the Moho.
rock above the fault surface moves downward in relation to the rock below the earths surface.
liquid layer -silicon, magnesium, oxygen and iron.
earthquake waves that move back and forth same direction are called seismic waves, too.
rocks above the fault are forced up[ and over the rocks below the fault.
In an earthquake waves that causes particles in the rock to move at right angles to the direction of the wave.
in an earthquake the energy waves that moves outward from the earth.
used to record, primary, seismic, secondary, & surface waves from earthquakes.
area on the other side of the earth where waves are not detected.
rock on either side of the surface move past each other w/ or down.
earthquake waves that travel outward from the epicenter. these wave a particular fashion back and forth movement.
Ocean waves generated by earthquakes
force of squeezing or pressing together.
