What is Geology? What does a Geologist do?
Geological development of an area
The geology of an area changes through time as rock units are deposited and added, and deformational processes change their shapes and locations. Deposition can happen when sediments settle on the surface of the planet and afterwards lithify into sedimentary rock, or when as submerged material like volcanic ash or lava flows quilt the surface. Igneous intrusions like batholiths, laccoliths, dikes, and sills, push upward into the overlying rock, and crystallize as they intrude. After the first sequence of stones has been deposited, the rock units can be deformed and/or metamorphosed. Deformation typically occurs as a result of horizontal shortening, horizontal expansion, or side-to-side (strike-slip) motion.
History of Geology
The study of the physical material of the Earth dates back to ancient Greece when Theophrastus (372--287 BCE) wrote the work Peri Lithon (About Stones). During the period, Pliny the Elder wrote in detail of the many minerals and metals then in practical use -- correctly noting the origin of amber.
Geologists work to understand the history of our world. The better they could understand Earth's history, the better they can foresee how processes and events of the past could influence the future.
Geology as a Career
If you're a pre-college student, you can prepare to become a geologist by performing well in all your classes. Science courses are particularly significant, but math, writing, and other areas are utilized by every geologist throughout every working day. If you're thinking about college or graduate school, there are a number of universities offering courses or programs in geology. Visit the web site of a school that offers a geology degree, get in contact with the geology section, let them know that you're interested and also make arrangements to see the campus. Don't be hesitant. Very good professors and schools are interested in being contacted by interested students.
