Chapter 2: Section 5 - Structural Geology and Your Community

PDF versionPDF version


In this section you will find materials that support the implementation of EarthComm, Section 5: Structural Geology and Your Community.

Learning Outcomes

  • Use a model that illustrates how rock layers appear when they are folded.
  • Use a model that explains the different ways that rock bodies can move relative to each other along a fault.
  • Analyze and interpret structural data on a geologic map and cross section to identify folds and faults in crustal rocks.
  • Obtain information about how the formation of folds and faults is connected to plate tectonic processes.
