GL 101 - Introduction to Geology


Description
This course is designed as a laboratory science course for non-science majors and as the first course for students interested in a degree in geology or a related science. The basic principles of geology are covered, including plate tectonics, earthquakes and volcanoes, minerals and rocks, the water cycle, glaciers, climate change, and geologic time.

General Education Requirement:
Natural Sciences
General Education Learner Outcomes (GELO):
3. Critical Thinking: Gather and synthesize relevant information, evaluate alternative perspectives, or understand inquiry as a means of creating knowledge, 7. Problem-Solving: Apply theory, calculation, or experimentation to demonstrate effective problem-solving
Course Learning Outcomes:
 

  1. Apply scientific principles learned in this course to assess the risk of geologic hazards including earthquakes, volcanoes, floods and mass wasting and be able to discuss various mitigation methods and predict outcomes
  2. Describe the theory of plate tectonics and use scientific data to identify phenomenon and geographic features associated with the three types of plate boundaries (GELO 3)
  3. Use observable and testable properties of common minerals and rocks to identify them and describe their environment of formation
  4. Analyze data from maps to identify the processes that shape the Earth’s surface, including weathering, erosion and deposition of sediment controlled by, gravitational, fluvial and glacial processes
  5. Examine data to determine the extent of human’s impact on Earth’s natural systems and its mitigation (GELO 7)
  6. Extrapolate the human impact on Earth’s natural systems for future generations
  7. Explain the nature, occurrence, and vulnerability of Earth resources, including water, mineral resources, and fossil fuels
  8. Evaluate data from rocks and rock outcrops to compile a geologic history of an area and its place in the geologic timescale.
