GEO 225 - Earth: The Physical Environment:
Introduction to geology and geological processes, Properties and processes of formation of rocks and minerals; dating of geologic events; the interior of the Earth; plate tectonics; earthquakes; deformation of rock and formation of mountain belts; origins of continents and ocean basins; weathering, erosion, and transport of sediment; resources of the Earth; alternative energy sources; the carbon cycle; global warming and other environmental issues. Three lectures, one three-hour laboratory, one field trip. This is an introductory course designed for undergraduate students who may wish to major in any aspect of the solid or fluid earth sciences.

GEO 552 - Global Seismology:
The use of seismic data to determine large-scale, three-dimensional earth structure and earthquake source parameters are examined. Moment-tensor representation of sources, free oscillations, surface-wave dispersion, and seismic tomography are studied. The emphasis in this graduate course varies from year to year, depending upon student interest. Topics are selected from the book Theoretical Global Seismology by F. A. Dahlen and Jeroen Tromp.

GEO 557 - Theoretical Geophysics:
Geophysical applications of the principles of continuum mechanics; conservation laws and constitutive relations and tensor analysis; acoustic, elastic, and gravity wave propagation are studied. The emphasis upon solid or fluid mechanics in this graduate course also varies from year to year depending upon student interests.
