Geoscientists study the Earth, including the materials that compose the planet, the processes that continuously change the planet, and the evolution of the earth and life through time. Because these studies involve investigations of relationships between the lithosphere, atmosphere, hydrosphere, and biosphere, the Geosciences are inherently interdisciplinary by nature and include aspects of chemistry, biology, and physics. Geoscientists also are addressing increasingly challenging problems that confront a growing human population as we begin the twenty-first century: dwindling water, mineral, and energy resources; earthquake prediction and natural hazard identification; human impacts on the environment at regional and global scales; and safe disposal of toxic and radioactive waste materials. The goal of the Department of Geosciences is to expose students to the complex interplay of Earth systems through active, hands-on learning. Therefore, a DePauw education in the Geosciences goes far beyond the traditional classroom. Students work in modern laboratories with extensive mineral, rock, fossil, and map collections. They use computers to model complex systems and simulate geological processes. They receive training on emerging technological tools such as GPS (global positioning systems) and GIS (geographic information systems). They participate on field trips that take them to some of the best geological exposures in the world. Many students spend a summer working closely with faculty on important research problems using state-of-the-art instrumentation. These student-faculty collaborations commonly result in student presentations at national meetings and co-authored publications in refereed journals.

Courses in Geology and Environmental Geoscience

Earthquakes and Volcanoes

An investigation of the theory of plate tectonics and how it explains the distribution of earthquake and volcanic activity throughout the world. Destructive historical earthquakes and volcanic eruptions are examined with consideration of the impact of these disasters on human populations. Advances in the prediction of earthquake and volcanic activity also are evaluated. May include lab some semesters.

Geology of America's National Parks

Study of the geologic history of America via the National Park System. The course focuses on origin and evolution of landforms in various national parks and the geologic processes that created and sculpted them. Park features serve as a point of departure for interdisciplinary discussions on society's impact on the lithosphere, hydrosphere, atmosphere and biosphere. May include lab some semesters.

Earth and the Environment

Includes laboratory. An introduction to the materials that make up the earth and the interplay between constructive and destructive processes that shape the earth, including plate tectonics. Laboratories include mineral and rock identification, field trips, and topographic map interpretation.

Weather, Climate and Climate Change

An introduction to the Earth's atmosphere through the study of weather, climate and climate change. Topics covered include atmospheric composition,structure and function, weather phenomena and climate, and natural and human-induced climate change. Global societal responses to rapid climate change are also discussed.

Introduction to Environmental Science

An introduction to the study of environmental science. Topics include matter, energy, ecosystems, human populations, natural resources, and the impact of human activity on the natural environment. Special attention is given to current environmental problems including air and water pollution, acid rain, stratospheric ozone depletion, climate change, deforestation, and species extinctions.

Off-Campus Extended Studies Course

Winter or May Term off-campus study project with a geosciences theme.

Topics

An exploration of selected topics in the geosciences. May be repeated for credit with different topics.

Energy, Environment, & Climate (formerly GEOS 190)

An introduction to energy resources and the environmental impacts of their use, particularly in relation to climate change. The course not only examines the importance of nonrenewable fossil fuels in modern industrialized societies, but also explores the potential economic costs and societal impacts of transitioning to renewable and sustainable sources of energy. In addition, given that climate change is the most significant global impact of our energy use, participants will consider human and natural climate-change agents, the evidence for climate change, and projections for climate change in the future.

First-Year Seminar

G. Geography. S. Geology. A seminar focused on a theme related to the study of geology or geography. Open only to first-year students.

Introduction to GIS

Includes laboratory. An introduction to Geographic Information Systems (GIS) and their applications. Emphasis on cartographic concepts, strengths and limitations of different GIS data formats, spatial statistics, and spatial analysis. Students use a variety of specialized GIS tools to solve spatial problems and map spatial phenomena. Prerequisite: GEOS 110.

Historical Geology

Includes laboratory. An introduction to earth history and the methods that geologists use to interpret the rock record and the fossil record. The origin and evolution of the earth and life through time are examined with emphasis on the interrelationships of earth history, evolution and plate tectonics. Prerequisite: GEOS 110.

Geologic Field Experiences

Includes laboratory. A. West Virginia B. Utah C. Nevada D. California E. Other. An introduction to field geology through intensive study of a geologic province. Students collect and interpret geologic data, construct geologic maps and cross sections, and read published professional papers in order to interpret the tectonic, stratigraphic and geologic history of a province. Topics include the Valley and Ridge Province in West Virginia, the Colorado Plateau Province in Utah, and the Basin and Range Province in Nevada. A week-long field trip to the geologic province is required during spring break. A course fee covers field trip expenses. May be repeated for credit with different topics. Prerequisite: GEOS 110.

Environmental Geology (formerly GEOS 109)

An intermediate examination of the processes that influence the physical and chemical nature of the Earth's surface with special attention given to the influence of human actions on the lithosphere, hydrosphere, and atmosphere. Students learn how the risks from natural hazards are assessed and minimized; understand the consequences of natural resource extraction; and consider the sources, transportation, fate, and remediation of waste and pollution in the environment. Real-world examples emphasize the importance of these topics for solving environmental problems. Prerequisite: GEOS 110 or permission of instructor.
