A Geologist is someone who studies the Earth and its structure. He is someone who looks at the major events that have affected the Earth since its formation. For example, a major event could be the eruption of Mt. erupting or it could be the movement of tectonic plates. They are all major events in the Earth’s history and have caused major climate changes and shifts in the structure of the Earth. Michael Osland has some excellent resource about the Geology and Earth structure.
There are several kinds of geology that a geologist may specialize in or he may choose to specialise in a particular field of geology. One of these fields is geodesy, which involves the study of the earth’s mineral content. These mineral content changes over time and with it changes in the Earth’s orbit around the Sun. Thus, geologists study earth processes such as the rate of change of mineral contents and earthquakes.
Another field of study of geology is earthquake geology. This is where the study and recording of earthquakes are done. Geologists record the location, magnitude of the event, and when, and any damages that were done by the earthquake. Through this method, they can determine the frequency and magnitude of future earthquakes in certain areas.
Some geologists may choose to specialize in one particular area of geology such as paleontology, which involves the study and examination of fossils. They look for evidence of ancient life forms and record the formation of rocks and other minerals in rock layers over time outdoors. They then record the fossils for further study. Paleontologists study the fossils found outdoors and record their findings in order to write about them in books and explain what they find in the scientific community.
One of the biggest roles of a geologist is to be the physical proof of the earth’s composition and structure. In fact, they should be able to verify the facts and figures that are recorded in the scientific research of the past years. If a piece of rock is found with the measurements and designation of an age that agrees with the scientific data, it is most likely a genuine piece of rock taken from the ground. A true geologist must be able to record the formation and survival of all kinds of creatures living in the earth’s crust.
Many people have given the job of researching and studying the earth’s surface a great deal of importance in the recent years. Some people think that it is their job because they are geologists, but some also think that civil engineers and/or marine geologists may be doing more important research. However, geologists should not be considered as the only ones who are studying earth’s crust and environment because there are so many different types of qualified people in this field.
