What is Seismic Waves and Earth about?

Seismology uses seismic waves generated by earthquakes to study the interior of the Earth. There are two main types of body waves - P waves which move through compression and S waves which move through shear. The speed of these waves increases with depth due to denser materials, allowing inferences about layer boundaries within the Earth from how waves refract at boundaries. Observation of wave refraction suggests drastic changes in seismic velocity at major discontinuities like the crust-mantle boundary an
