GEOL 100. Earth: Exploring a Dynamic Planet (1). Exploration of geologic processes that shape our dynamic planet and how they interact as a system. Topics include plate tectonics, deep time, climate, volcanoes, earthquakes, streams and groundwater, glaciers, natural resources, and the interactions between geologic processes and human populations. The class emphasizes both global systems and the geology of southern Wisconsin. We focus on using scientific methods to decipher complex interactive processes and developing skills for observation and analysis in the field and laboratory. One Saturday or Sunday field trip. Students who have credit for Geology 110 may not take this course for credit. (4U) Offered yearly.
GEOL 105. Evolution of the Earth (1). The recent revolution in geologic thinking that was brought about by the ideas of sea-floor spreading, heat flow through the Earths crust, reversals of the Earths magnetic field, and earthquake studies allows a synthesis of the Earths evolution. Information from rock associations, fossils, stratigraphic correlations, and radioactive-age determinations forms a logical picture of the co-evolution of the Earths lithosphere, hydrosphere, atmosphere, and biosphere. The human dimension of historical geology is revealed in tracing the development of the concept of time. Lecture, discussion, laboratory, field study. One Saturday or Sunday field trip. (4U) Offered yearly.
GEOL 110. Environmental Geology and Geologic Hazards (1). Application of geologic principles to help in understanding the response of our environment to natural and anthropogenic forces of change, and proper constraints we should exercise in being good stewards of the Earth. Natural resources, floods, volcanic activity, earthquakes, landslides, coastal processes, and pollution are among the topics considered, with emphasis on current events.

GEOL 210. Paleontology (1). The history of life from its origins to the present. The preservation, distribution, and identification of invertebrate fossils and of selected vertebrate and plant fossils. Competing evolutionary theories are evaluated in the perspective of geologic time. Fossils are studied as once-living organisms adapting to changing ecosystems. Lecture, discussion, laboratory, field study. One Saturday or Sunday field trip. (Also listed as Biology 210.) Offered alternate fall semesters. Prerequisite: Geology 105 or Anthropology 120 or 1 course in biology. Geology 100 or 110 recommended.
GEOL 215. Field Geology (1.25). Techniques of collecting, recording, and presenting geologic data. The use of the Brunton compass, magnetometer, GPS, surveying techniques, and surface and groundwater hydrogeology field methods. The interpretation of data as plotted on maps, sections, and aerial photographs. Field observations and measurements are synthesized with maps and cross-sections in written reports. Lecture, laboratory, field study. Five-week course offered alternate summer terms. Prerequisite: 2 units in geology including Geology 100 or 110.
GEOL 220. Structural Geology (1). Mechanical principles applied to folds, faults, joints, igneous plutons, and secondary structural features of the Earth.
