What is geology ?

What is geology? ? .. The question remains often I get every time I met with new people outside of the scope of my day-to-day relationships. however, there also have an idea about the geology in the course of the disaster that befell experience. well, a little more I can say "yes .. The application of geology "because in geology indeed learn about disasters and mitigation efforts. however the geological world not just only that, because the geology related to physics jamant (learn the styles of the Earth), chemical (learn the material making up the Earth) and biology (study of the past through the fossil record as well as the earth's history).by Whitten and brooks (1972), who studied geology is the science of the earth begins its origins formation, structure, composition and formation history (commencing change of life), and the processes that lead to the current situation of the earth like this. because in fact our world is not static or stationary, always take small changes, slowly but continuously or switch quickly, large and sporadic.

 

among the plans so popular in geology, uniformtarianisme raised by the father of geology, James Hutton (1785) and so the plan is very often mentioned as well as easy to remember (I mean by me personally, hehe ..) that "the present is the key to the past "that the forces and processes that shape the Earth's surface like that we observe today, it's been running since the formation of the earth. mean, what is going on at this time we can use to reconstruct past conditions of the earth at the time. and at least be able to give us an idea of ​​how the condition of the earth in the days to come dengaan other words, the present is the key to the past and to the future.

a geologist or geologiawan working in every corner of the world, starting from the top of which is covered by the arrangement of the ice, to the volcano remained active up to the basic deep sea. trying to know and understand the entire system running on the earth as well as documenting the long history of the earth as well as complex. by because it is done research on every corner that could be achieved, for places like that can not be achieved under the earth's surface, the investigation carried out by a step in the drilling done.
besides acting also important geologist in mineral exploration are as well as the world, geologists are doing research to know there are oil fields are new, coal, geothermal (geothermal), water sources, and where there are mineral deposits (ore deposit), precious metals and so on.
in the construction business, geologists also have an important role. for example, to plan the construction of a large building structure (like a giant dam), or vital buildings to another, then the civil engineering can take the place of geological data. good form stability location, location of buildings associated with the right geological structure that develops at the site.
most branches of science including geology:

1. Mineralogy, minerals studied starting from the formation history, constituent composition, crystal structure and physical properties of the character. mineralogy is to learn basic rock, because rock mineral is a constituent component.
2. Petrology, who learned about the science of rocks. how the history of the formation, composition, structure and the structure and classification.
3. Paleontology, learned about past life and then think of the fossil record that happened. studying fossils, we can know the age of the rock bedding or much less a place and its history. because a group of fossils can be used to correlate rock layers that exist in one location.
4. Geomorphology, learn about the form of the earth's surface and the natural processes that shape it.
5. Stratigraphy, learn about the composition of rock bedding, deployment, composition, thickness, age, diversity and correlation of rock composition.
6. Geological structure, learn about architectural form as well as the configuration of the earth's surface rocks in the earth's crust is deformed, where the composition of natural rock fractures, displaced or folded so the mountain folds.
7. Geophysics, related to the physical character of the earth. counted therein seismicity, gravity, kemagnitan or temperature gradients.
8. Geochemistry, learn about the chemical elements making up the earth, where the elements of high economic value, the isotope that is in the earth as well as the spread of specific elements in a variety of areas. geochemical exploration methods greatly help in search of minerals and hydrocarbons.
9. Geological engineering, learned about civil engineering according to geological data available.
10. Volcanology, learn about the formation of volcanoes, form and composition, eruption types, materials produced by volcanoes, the effects caused when the eruption took place and how the mitigation effort during a volcanic eruption.
11. Geological disaster management, learn about the various types of geological disasters, trigger factor and mitigation efforts.
12. Tectonics, learn about the earth's crustal deformation takes place, the theory of plate tectonics and the movement.
13. Geological history, study the sequence of units of time and the change of the earth's history.
14. Geology of oil and gas, application of geological knowledge to trace the sources of oil and natural gas.
15. Geological environment system, the application of the science of geology on the human environment following system aspects that support.
