Oregon is one of the few states where all three types of rocks (igneous, sedimentary, and metamorphic) have formed. Oregon's has had it all – basalt eruptions, massive floods, volcanic eruptions, earthquakes, tsunamis, glaciers, and tectonic uplift. In fact, because of its amazing geological legacy, Oregon is one of the few places on earth that has examples of nearly all the earth's main soil types.
This unit provides great hands on opportunities to learn about soils – with an Oregon twist. Whenever possible, Oregon images and examples have been provided to make the lessons more relevant to our state's students while meeting standards.
Hands on lessons, Oregon photos, PowerPoint slides with presenter's notes, worksheets and maps are provided free to download from the Resources Section.
