Geology is divided into several fields that can be grouped under the main headings of physical and historical geology. Applied Geology Applied Geology is geologic knowledge to solving geologic problem. In other words, application of various fields of geology to economic, engineering, water-supply, or environmental problems; geology related to the human activity. METHODS OF GEOLOGY Geologists use primary data associated with petrology (the study of rocks), stratigraphy (the observe of sedimentary layers), and structural geology (the have a look at of positions of rock devices and their deformation). In many cases, geologists additionally take a look at contemporary soils, rivers, landscapes, and glaciers; inspect past and contemporary life and biogeochemical pathways, and use geophysical techniques to investigate the subsurface.
