Knowledge of earth's interior is mostly derived from indirect evidence involving the analysis of seismic waves the scientific study of rock strata (layers) is known as. Seismic study of earth’s interior let’s now utilize your knowledge of seismic velocity, refraction, and reﬂection to see how each of the major layer boundaries inside the earth was discovered discovering the crust-mantle boundary. The distance from earth's surface to its center is about 3,975 miles (6,395 kilometers) scientists have divided the interior of earth into various layers, based on their composition the crust, or outer portion, varies in depth from 5 to 25 miles (8 to 40 kilometers) below the crust is the mantle . Extensive knowledge of the earth’s interior has been derived from a variety of measurements, however, including seismic waves produced by quakes that travel through the earth, measurements of the flow of heat from the earth’s interior into the outer crust, and by astronomical and other geologic considerations.

The high temperatures in the earth's interior heats up underground water leading to the formation of springs and geysers from the above example, we see that having the knowledge about the interior of the earth enhance our knowledge about the relief features of the earth. Knowledge of earth’s interior is derived primarily from analysis of the seismic waves that propagate through earth as a result of earthquakes depending on the material they travel through, the waves may either speed up, slow down, bend, or even stop if they cannot penetrate the material they encounter.
