Advances in seismology, computer modeling, and mineralogy and crystallography at high temperatures and pressures give insights into the internal composition and structure of the Earth.Seismologists can use the arrival times of seismic waves in reverse to image the interior of the Earth.Geology, a major academic discipline, also plays a role in geotechnical engineering.

Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates.They also provided a driving force for crustal deformation, and a new setting for the observations of structural geology.The power of the theory of plate tectonics lies in its ability to combine all of these observations into a single theory of how the lithosphere moves over the convecting mantle.Transform boundaries, such as the San Andreas Fault system, resulted in widespread powerful earthquakes.Plate tectonics also has provided a mechanism for Alfred Wegener's theory of continental drift, in which the continents move across the surface of the Earth over geologic time.

More recently, seismologists have been able to create detailed images of wave speeds inside the earth in the same way a doctor images a body in a CT scan.
