Body waves. Body waves are of two types: compressional or primary (P) waves and shear or secondary (S) waves. P- and S- waves are called body waves because they can travel through the interior of a body such as the Earth's inner layers, from the focus of an earthquake to distant points on the surface. The Earthâs molten core can only be travelled through by compressional waves.

When a wave moves faster than the local speed of sound in a fluid it is a shock wave. Like an ordinary wave, a shock wave carries energy, and can propagate through a medium; however it is characterized by an abrupt, nearly discontinuous change in pressure, temperature and density of the medium.
