Geology

Course Description

Geology is a course that explores the origins and the connections between the physical, chemical, and biological processes of the Earth system. The student will investigate

  • Maps
  • Matter and Minerals
  • Rocks and the Rock Cycle
  • Geologic History
  • Plate Tectonics
  • External Landform Morphology

Students will experience the content of Geology through investigations and observations both in the field and the laboratory and through open-ended problem solving via cooperative learning and individual research.

Students will focus on the physical aspects of Earth processes and cycles. The participants, will understand the importance of these processes and how they have and will continue to influence mans very existence and well being. This will enable them to make sound decisions relative to their community as well as the Earth’s environment as a whole. Geology will provide a means of connecting all disciplines of science including biology, chemistry and physics. Geology also provides many areas of opportunity for personal career choices.
