Do geologists use radiometric dating
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.In practical terms, geology is important for mineral and hydrocarbon exploration and exploitation, evaluating water resources, understanding of natural hazards, the remediation of environmental problems, and providing insights into past climate change.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.
Geology can also refer to the study of the solid features of any terrestrial planet or natural satellite, (such as Mars or the Moon).It can then be turned into a metamorphic rock by heat and pressure that change its mineral content, resulting in a characteristic fabric.All three types may melt again, and when this happens, new magma is formed, from which an igneous rock may once more crystallize.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.
They also provided a driving force for crustal deformation, and a new setting for the observations of structural geology.
