Many people who didn't know much about Geology got hooked by taking an introductory class.

General Courses

G103 Earth Science Materials and Processes

(3cr.) N & M Introduction to origin and classification of minerals and rocks. Relationships between rock types, rock structures, surficial geological processes of running water, subsurface water, glaciation, wind, tides, and landform evolution. Geologic time.

G104 Evolution of the Earth

(3 cr.) N & M Earth’s history interpreted through five billion years. Deductive approach to understanding the significance of rocks and fossils and reconstructing the plate-tectonic origin of mountains, continents, and ocean basins. A survey of events in earth's evolution relevant to contemporary environmental concerns. Two lectures and one laboratory each week. Credit given for only one of the following: G104, G112.

Summer School Can Be Cool: IU's Judson Mead Field Station in Montana offers inspiring and fun field classes. See the site for course listings.

G105 Earth: Our Habitable Planet

(3 cr.) N & M Introduction to planet Earth as a dynamic and complex global system. Course materials will demonstrate physical and chemical linkages between biosphere, atmosphere, hydrosphere, and geosphere that directly impact lifestyles of human populations at time scales of years to centuries.

COLL-C 105 Earth Processes and Planets

(3 cr.) N&M Processes that operate and have operated on, in and around the Earth, Mercury, Venus, the Moon, and Mars contributing to their evolution through approximately 4.56 billion years; evaluate the evidence using principles of geology, chemistry, physics, astronomy, biology, geography and mathematics. Critical approach course for non-science majors. Lecture Tues/Thurs. (Fall) website

G116 Our Planet and Its Future

(3 cr.) N & M The interaction between geologic and environmental processes in the earth. Special emphasis on how these processes affect public policies and laws. Multimedia exercises and videotape presentations (made specifically for this course) are included.


G112 Historical Geology

(3 cr.) N & M Principles of interpreting earth history from geological data. Geologic time, biological evolution, plate tectonics, and ancient environments. Two lectures and one laboratory per week. One required field trip. Credit given for only one of the following: G104, G112.

G131 Oceans and Our Global Environment

(3 cr.) N & M Introduction to oceanography, with emphasis on: ocean-atmospheric interaction and global climate, plate tectonics and morphology of the ocean basins, marine geology, energy resources, environmental problems due to sea level rise, coastal erosion, oil spills, and life in the sea.

G141 Earthquakes and Volcanoes

(3 cr.) N & M Examination of the causes and effects of earthquakes and volcanic activity. Impacts of earthquakes and volcanic eruptions, including secondary effects such as landslides, mudflows, and tsunamis; climatic effects; energy/mineral resources; and social disruption. Mitigation of effects of natural disasters.

G171 Environmental Geology

(3 cr.) N & M Examination of natural and man-induces geologic hazards: earthquakes, volcanoes, landslides, and land subsidence; environmental issues, disposal and management of solid, chemical, and radioactive waste, acid mine drainage as well as the environmental impact of mineral extraction and water resource utilization.
