Geologists

Geology is a young science, first developed by early mining engineers. In the late 18th century, scientists such as the German geologist A. G. Werner and James Hutton, a retired British physician, created a sensation with their differing theories on the origins of rocks. Through the study of fossils and the development of geological maps, others continued to examine the history of the earth in the 19th century.

From these beginnings, geology has made rapid advances, both in scope and knowledge. With the development of more intricate technology, geologists are able to study areas of the earth they were previously unable to reach. Seismographs, for example, measure energy waves resulting from the earth's movement in order to determine the location and intensity of earthquakes. Seismic prospecting involves bouncing sound waves off buried rock layers.
