Mapping the Earth's internal structure.
Seismic waves such as those produced by earthquakes.
scientists use seismic waves to map earths interior by seismographs that measure the times at witch seismic waves arrive at different distances from an earth quake.
Scientists determined that the Earth has layers through studying how seismic waves travel. These seismic waves differed depending on how thick the layer was.
The paths of seismic waves

the Mohorovicic (Moho) discontinuity
By studying how seismic waves travel through the Earth's interior.
seismic waves that travel through the earth
seismometer, also known as a seismograph. which record seismic waves
A seismograph is an instrument that records movements within the earth. A seismogram is the actual recording that scientists look at when studying earthquakes.
Seismic waves are any waves that travel through the Earth. As such all earthquake waves are seismic waves, however not all seismic waves are caused by earthquakes.
(not seismic, seismic wave)Seismic waves are waves of energy that travel through the earth.
