Geology is the study of the Earth, the materials of which it is made, the structure of these materials, as well as also the processes acting upon them. It includes the analysis of organisms that have inhabited our planet. An important part of geology is the study of how Earth's materials, structures, procedures and organisms have changed over time.
Geological development of an area
The geology of an area changes through time as rock units are deposited and inserted, and deformational processes change their shapes and locations. Rock units are first emplaced either by deposition onto the surface or intrusion into the overlying rock. Deposition can happen when sediments settle onto the surface of the Earth and later lithify into sedimentary rock, or when as volcanic material such as volcanic ash or lava flows blanket the surface. Igneous intrusions such as batholiths, laccoliths, dikes, and sills, push upward into the overlying rock, and crystallize as they intrude. After the initial sequence of stones was deposited, the stone units can be deformed and/or metamorphosed. Deformation typically occurs as a result of horizontal shortening, horizontal expansion, or side-to-side (strike-slip) movement.
History of Geology
The study of the physical substance of the Earth dates back at least to ancient Greece when Theophrastus (372--287 BCE) composed the work Peri Lithon (About Stones). During the period, Pliny the Elder wrote in detail of the many metals and minerals afterward in practical usage -- correctly noting the source of amber. Geologists work to understand the history of the world. The better they can understand Earth's history, the greater they can foresee how processes and events of the past could help determine the future.
Geology as a Career
Geology could be a very interesting and satisfying career. The minimal training required is a four-year school degree in geology. Pre-college students who are interested in getting geologists should have a full program of college preparatory courses, especially those in mathematics, science, and writing. Courses related to computers, geography and communication are also valuable. You can interact with Geologists on Geology Buzz
or some other Geology forum. Geologists work in a variety of settings. These include: natural resource companies, environmental consulting companies, government agencies, non-profit organizations, and universities. Most geologists do field work at least part of the moment. Others spend their time in laboratories, classrooms or offices. All geologists prepare reports, do calculations and use computers.
Although a bachelor's degree is needed for entry-level job, many geologists make master's and/or doctorate degrees. The advanced degrees offer a higher level of training, frequently at a geology specialty area such as paleontology, mineralogy, hydrology, or volcanology. Advanced levels will often characterize the geologist for supervisory positions, research assignments, or teaching positions at the college level. These are a few of the most sought-after jobs within the area of geology. Employment opportunities for geologists are extremely good. Many geology graduates with a strong academic foundation and good grades don't have any difficulty finding employment if they are eager to proceed to some place where work can be obtained.
If you're a pre-college pupil, you can prepare to be a geologist by performing well in all of your courses. Science classes are especially important, but mathematics, writing, and other areas are utilized by every geologist throughout every working day. If you are thinking about college or grad school, there are many universities that offer courses or programs in geology. Go to the web site of a school that offers a geology degree, get in contact with the geology section, inform them you are interested and make arrangements to visit the campus. Do not be hesitant.
