Geology

- science and study of the solid matter that constitutes the Earth. Encompassing such things as rocks, soil, and gemstones, geology studies the composition, structure, physical properties, history, and the processes that shape Earth's components. Geologists have established the age of the Earth at about 4.6 billion (4.6x109) years, and have determined that the Earth's lithosphere, which includes the crust, is fragmented into tectonic plates that move over a rheic upper mantle (asthenosphere) via processes that are collectively referred to as plate tectonics. Geologists help locate and manage the Earth's natural resources, such as petroleum and coal, as well as metals such as iron, copper, and uranium. Additional economic interests include gemstones and many minerals such as asbestos, perlite, mica, phosphates, zeolites, clay, pumice, quartz, and silica, as well as elements such as sulfur, chlorine, and helium - Wikipedia.

Geomorphology

processes that impact large areas such as mountain building due to plate tectonics, local events such as mass wasting events on hill slopes, landforms in Ohio and their formation

Climate Change

climate change during the Holocene, different climate archives and their use to establish past climatic changes, glacier fluctuations, tree-rings, lake and marine sediments, pollen, and ice cores, current knowledge of Holocene climate change in British Columbia and surrounding areas, larger spatial and temporal patterns using examples from Europe, the Southern Hemisphere and the tropics, Possible forcing mechanisms responsible for the reconstructed changes, future climate change scenarios and their environmental consequences

Environmental Geology

relationship between society and the earth: geologic hazards, resources, environmental challenges, evolution and structure of our planet's atmosphere, effects of anthropogenic perturbations in the systems such as the introduction of pollutants in groundwater or land degradation associated with agriculture
