what does a geologist do?

The scientific study of the origin, history, and structure of the earth. \nThe structure of a specific region of the earth's crust. \nA book on geology. \nThe scientific study of the origin, history, and structure of the solid matter of a celestial body.

Scientists look for a great many things.\n\nScientists want to know what the Earth used to be like.  They look at fossils, among other things, to find out.\n\nPretty much every aspect of fossils is examined.  Given any on fossils, scientists will be trying to determine:\n\n* How the individual lived.\n* How it died.\n* What died with it.\n* What it says about the larger world.\n\nFor instance, scientists know that some Sauropod dinosaurs (ones like Brontosaurus) lived in herds because they frequently trampled on each other's tails.  Sauropod tails have large numbers of these minor injuries, suggesting such tail damage was common.\n\nA single fossil will be examined for bone damage to see what killed it.  Sometimes, they can identify the species of animal that attacked the the fossil.  They also look for traces of scavengers afterwards, and even decay processes!\n\nFossils of animal dung are examined to see what was being eaten.  These are called coprolites.\n\nFossils of "supersized" insects in the ancient past tell us that the oxygen in the atmosphere used to be much higher.  Today, an insect that large would suffocate.\n\nEvery aspect of a fossil is examined.  How big it was, how fast it grew (from growth lines), everything.\n\nIt's a detective story!  Come help us figure it all out!

Gemology (gemmology outside the United States) is the science, art and profession of identifying and evaluating gemstones. It may be considered a branch of mineralogy. Some jewelers are gemologists and are qualified to identify gems.

The Natioanal Park Service employees two types of civil engineers, Construction and Design.\n\nConstruction Civil Engineers are responsible for conducting on-site inspections of construction sites and monitoring of construction activities in the NPS system.  They are the interface between the construction workers in the parks and the NPS.\n\nDesigns Civil Engineers create the plans and monitor construction activites for civil type projects in the parks (i.e. roadways, utilities, drainage, etc.).

Paleontology is the study of fossils.

Seismologists can do so. They have special adapted equipment to measure the tremours of the earth with a luminograph(i'm not sure about the spelling). It is a pencil sketching graphs on paper always and when the ground trembles, there is an unevenity in the graph. Seisomologists also can see how the position of coastal plates have changed to predict earthquakes.

When sediment containing iron is deposited, the iron aligns itself with the earth's magnetic field like a compass does.  When the sediment hardens, geologists are able to collect the rock, examine the alignment of the iron it contains, and try to calculate the nature of the planet's magnetic field (e.g., its strength, the location of its poles) at the time that sediment was deposited.

Igneous, they tell us a lot about what the age of the Earth and location of the poles.\n\nSedimentary, tell us the climate of an area and preserve fossils.\n\nMetamorphic, they look cool but are hard to tell anything from.  Their general location tells us of orogenies and faults.\n\nAll rocks are important and different geologists study different things.  Oil bearing shale is important to some geologist since if we can figure out an economical method of extraction we wouldn't be dependent on other countries for oil.\n\nGeology is like a big puzzle, and it's interesting seeing how the pieces fit together.

Search for oil, gold or other precious metal deposits.  Survey sites for faults before putting in a building, road, dam.  Check for landslide or erosion hazards.  Explore volcanoes for eruption risks.  And many more.

Basically, achitectural engineers design and guide the construction of buildings, bridges, monuments, etc. to function properly, withstand natural forces, and be asthetically pleasing. Teams of engineers, architects, and support staff  work together to accomplish this task.\nThis is a lofty goal you have set for yourself. If you are detemined enough, I know you can do it. Best wishes and Go Owls!!!

Can you scan it and post a picture?\n\nYou could look in the yellow pages under "Geologist."\n\nYou could take it to the geology department of a college or university.

Site investigation = \nIt understands the topographical, plani-altimetric mapping of the land.\nYou must make geothecnic soundings to define the quality of the ground and to give subsidies for the project of foundations.\nIt could be usefull a geologic mapping (with descritions of lithogy, rock situation - geologic imperfections and breakings)\n\nSite evaluation = There are a International Association to define the standards on Evaluation (Appraising).\nThe evaluation can determine the value of this property, using an experienced evaluator and recognized technis.

Petroleum Engineers... they hunt for good areas of oil reserves based on the type of ground layers... geology...

A mineral.  It's one of the characteristic differences between a rock and a mineral, that the mineral has a defined composition that will crytsalize.

There is no true name for a rock collector with the word rock in it. The technical name is a petrologist. However rock collectors are often known as "Rock Hounds"

Someone who collects samples of the core drilled out when drilling for oil. this gives a sample which tells what kinds of rock or soil is being drilled through and if gasses are present. Also a seismic graph is kept. These things are used to log what is being drilled through and lets you know what can be expected as drilling proceeds.

Oceanology is the study of the oceans; geology is the study of the earth; and meterorology is the study of the planets, meteros and the stars; so you have sea, land and the stars--almost like the SEALS--exceptionally well trained military men who serve on the sea, land and air.
