Seismic waves have helped scientists learn the various densities of the Earth's many layers because the speed of primary shock waves moving through the earth generally increases with depth. This is because as density increases, seismic wave velocity increases. While P-waves travel through the Earth's crust at an average of about four miles (6.4 km) per second, they reach an average of seven miles (11.3 km) per second at the center of the Earth. When the shock waves suddenly shift in direction and speed, scientists are able to determine the depths at which Earth's various layers are located.
Three different types of waves travel away from the focus of a seismic event. These waves travel at different speeds. In addition to surface waves, the waves that are proving critical to providing evidence about the interior of the Earth are 'P' waves (P standing for primary or pressure), and 'S' waves (S for secondary or shear). P-waves are faster than S-waves.
P-waves can travel through solid rock and fluids, and their speed will vary depending on the density of the rock through which they travel; increased speed will indicate increased density, thus providing information about the density and possible mineralogy of Earth's various layers.
S-waves cannot travel through fluids, thus when an S-wave encounters the outer core of the Earth (liquid iron and nickel), it is disrupted, indicating the boundary between the mantle and outer core and the boundary between the inner core and outer core. The effect observed from the motion of S-waves reveals a 'shadow zone', opposite to where they originate.

How do seismic waves provide valuable scientific data?
Seismic waves can reveal information about Earth's interior structure by traveling at different speeds and being reflected and refracted by different layers of rock. By studying how seismic waves travel through the Earth, scientists can determine the composition, density, and temperature of various layers and help understand processes like earthquake formation and plate tectonics. This data is crucial for understanding Earth's dynamic processes and for assessing geological hazards.
