Course Description
This course is concerned with Earth history and the events that have shaped the development of the Earth. Topics include: the origin of the Earth, movement of Earth's tectonic plates over time, origin and evolution of life, mass extinction events, and ancient climates. Techniques used to date and interpret events of the past and reconstruct ancient environments will be discussed. The course includes practical hands-on labs. A field trip may be required.
Course Content
  • Origins: Origin of the solar system and planet Earth, origin of life, evolution.
  • Rocks and Minerals: Composition, texture/physical properties, classification and identification.
  • Sedimentary Rocks and Environments: Composition, texture, classification, identification, formation, weathering and erosion, soils, sedimentary processes and structures, depositional environments and erosional/transport agents.
  • Interior of the Earth: Structure of the Earth, plate tectonics, composition and structure of oceanic and
    continental crust, structural deformation (e.g., orogenies, rifting).
  • Time: Geologic time scale, relative and absolute dating.
  • Stratigraphy: Stratigraphic principles, lithostratigraphy, biostratigraphy, lithofacies, biofacies, correlation.
  • Paleontology: Fossil observation, description, identification.
  • Ancient environments: Paleoenvironments, paleobiogeography, paleoclimate.
  • Major events of Earth history: Extinctions, supercontinents, glaciations, etc.
Learning Outcomes

After successfully completing EAES 1121, a student will be able to:

  • Describe the history of important events and people involved in the development of early geological concepts and the geologic time scale. Explain the difference between uniformitarianism, actualism and catastrophism.
  • Recite the geological time scale in terms of eons, eras, periods and Cenozoic epochs.
  • Describe, identify and classify the most common rocks and minerals. Explain the formation of sedimentary rocks and stratified and cross-cutting igneous rocks.
  • Describe the underlying principles of stratigraphy and fossil succession and apply them to sedimentary successions (stratigraphic sequences). Interpret stratigraphic sequences in terms of changes to paleoenvironment and paleolandscape. Correlate stratigraphic sequences.
  • Describe, identify and classify common fossil organisms (classification based on kingdom, phylum, class and order). Explain the basic principles of evolution and extinction.
  • Describe the theory of plate tectonics and how it relates to rock forming processes.
  • Recite and describe key climatic, tectonic and evolutionary events in Earth's history.
Means of Assessment

Evaluation will be carried out in accordance with Douglas College policy. The instructor will present a written course outline with specific evaluation criteria at the beginning of the semester. Evaluation will be based on the following:


Lecture and lab assignments, homework, project, term paper 10 - 30%
Lab exams, quizzes 20 - 40%
Midterm exam 20 - 25%
Final exam 30%
Textbook Materials

Students should consult the bookstore for the latest required course materials, including the textbook.

Levin, H.L., The Earth Through Time; Wiley Publishing, latest edition, or an equivalent text.
