Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates.Geologists use a wide variety of methods to understand the Earth's structure and evolution, including field work, rock description, geophysical techniques, chemical analysis, physical experiments, and numerical modelling.The majority of research in geology is associated with the study of rock, as rock provides the primary record of the majority of the geologic history of the Earth.There are three major types of rock: igneous, sedimentary, and metamorphic.

Transform boundaries, such as the San Andreas Fault system, resulted in widespread powerful earthquakes.This rock can be weathered and eroded, then redeposited and lithified into a sedimentary rock.It can then be turned into a metamorphic rock by heat and pressure that change its mineral content, resulting in a characteristic fabric.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.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.
