This course will cover various topics related to Air Quality. Initial lectures will cover the history of air pollution, discussions of the Clean Air Act and composition of the atmosphere. We will then progress to discussion of atmospheric pollutants and sources of those pollutants. Additional topics will include: fate of atmospheric pollutants (transport and dispersion mechanis will include: fate of atmospheric pollutants (transport and mechanisms), effects of air pollution (health and environmental effects), urban smog, acid rain, climate change, ozone depletion in the stratosphere, air quality criteria, and engineering controls.

Origin and diversification of land ecosystems. Interaction between plants and animals. Effects of past climatic change and other external factors. The importance of past changes in land ecosystems to our understanding of current global change.

Occurrences and origins of igneous and metamorphic rocks; phase equilibria in heterogeneous systems. Laboratory study of rocks and thin sections as a tool in interpretation of petrogenesis. Two field trips.

This course deals with the study of the two main parts of Earth's climate system, the atmosphere and the ocean. It explores, qualitatively and quantitatively,the physical laws, geological and geographical processes, and mass and energy budgets that govern these two parts and their combined influence on Earth's past and present climate. Main topics covered include, but not limited to, properties of air and water; physical balances; equilibrium states; transport of heat and mass; clouds; precipitation; storms; regional and global climate; ozone layer; seasons and climate; weather forecasting; atmospheric optics; ocean currents; ocean bathymetry, salinity, and atmospheric forcing; history of Earth's changing climate in the geologic record, global warming, and how climate impacts humans and how do humans impact climate.
