What is a seismograph? It'san instrument that measures and records details of earthquakes, such as force and duration.Seismology is the study of earthquakes and seismic waves that move through and around the earth. ... Body waves can travel through the earth's inner layers, but surface waves can only move along the surface of the planet like ripples on water. Earthquakes radiate seismic energy as both body and surface waves What does a seismograph do? Seismographs can detect quakes that are too small for humans to feel. During an earthquake, ground-shaking seismic waves radiate outward from the quake source.
Hey Mr. Koolaid, what's the difference between S and P waves.
The difference between S and P waves is the S waves go through the crust and upper mantle (lithosphere) and come back up. The P waves go to through the crust and all the way through the mantle. We covered this yesterday while you were gone.
