The seismic waves that travel through Earth’s interior are
known as the P waves and the S waves, these seismic waves have differences,
first the P waves compress and enlarge the foundations(rocks) as they move
through it, while the S waves, shakes the particles of their medium up and down
and side-by-side. P waves can travel through solid granite, magma, water or
even air, while S waves can only travel through solids, they are unable to
travel through fluids. The P waves are the fastest of all known seismic waves,
it is the first seismic wave to register on the seismograph, while the S wave
is the second one.
