In this section you will find materials that support the implementation of EarthComm, Section 3: Sedimentary Rocks and the Geologic History of Your Community.
- Use models that examine the processes that form sedimentary rocks.
- Carry out an investigation that identifies a variety of sedimentary rock specimens according to their physical properties.
- Analyze data on a geologic map and legend to locate sedimentary rocks in your region.
- Obtain information about how the formation of sedimentary rocks is connected to plate tectonic processes.
- To learn more about sedimentary rocks and energy resources, visit the following websites:

Prof. Allen Glazner's collection provides images of sedimentary rocks (click on the slide viewer for captions).
Characteristics of Sedimentary Rocks, University of British Columbia Okanagan
The properties of sedimentary rocks are introduced in this illustrated section from an online textbook (Fundamentals of Physical Geography, Michael Pidwirny, University of British Columbia Okanagan, Canada). Key terms are linked to definitions in an accompanying glossary.
Chemical Sedimentary Rocks, California State University Long Beach
Explains the formation of chemical sedimentary rocks.
Classifying Sedimentary Rocks
Sedimentary Rocks, Pamela Gore, Georgia Perimeter College
Part of a physical geology course, these notes provide a brief, illustrated introduction to sedimentary rocks, covering terrigenous sedimentary rocks (also called detrital or clastic), chemical/biochemical sedimentary rocks (including the evaporites, the carbonates and the siliceous rocks), organic sedimentary rocks, and other types.
Sedimentary Rocks and Sedimentary Rock Classification, Ocean Drilling Program
Describes the major types of sedimentary rocks and the different settings in which they form.
Structures and Bedforms in Sedimentology, USGS
Provides information, including animations, on structures in sedimentary rocks such as cross bedding and what they indicate about past currents.
