This course in Earth Systems explains the geology of the Earth in the context of the natural environment. The course covers basics of the solid Earth (rocks, minerals, volcanoes, and earthquakes); surface systems (biosphere and weathering), fluid systems (surface water, oceans, groundwater, atmosphere; and the dynamic Earth (plate tectonics, energy transfer, and climate change). It discusses how the physical characteristics of the Earth and human interactions impact environmental change, global warming, and other issues. The course includes a laboratory providing hands on experience with the subject matter. This course satisfies elective credit in the Environmental Science track for the ENST major and minor. This course satisfies the Core Exploration requirement in the Natural Sciences with Laboratory.
