p waves and s waves can be used to determine ____

the location of an earthquake

p waves and s waves can theorize _____

the structure of the center of the earth

a seismogram records _______

the time when the first primary wave arrives

the deeper into the mantle the wave goes, the greater the pressure is

the wave speed increases

S waves

transverse

When do waves refract?

when going from a solid to a liquid

subduction zones

S waves can only travel through

solids

fastest seismic wave

p wave

second fastest type of seismic wave, and originate at the earthquake focus

s waves

a vibration produced by an earthquake

seismic wave

an instrument that measures and records ground vibrations

seismograph

seismic waves can be measured and recorded by devices called ______. These devices rcord the seismic wave vibrations as jagged lines on paper. the stronger the vibrations, the more the jagged lines. these recordings are called ______.

seismographs; seismograms
