Document Summary
Applied geology: using knowledge of earth to benefit humanity, i. e reduce exposure and obtain resources. The study of earth hazard and resources; geo = earth and logos = knowledge of. Processes: earthquakes, volcanoes, and erosion are each examples of internal and surface earth processes. Internal earth would be plate tectonics as a result of movement to heat. Surface earth would be weathering and subsequent erosion and a result in movement of water. Goals of environmental geology include: to ensure continued availability of resources, to minimize problems associated with resource use. Geologic processes occurring become hazardous when people are surrounding. By studying geologic record (rocks), geologists can study earth processes and history. Thereby giving the ability to predict where an event may take place, what the effect is, and how often to expect an event given the size. These processes produce resources that we need, including energy, minerals, soil, air, water, and building material.
