The Geologic Story of South Dakota

After a brief introduction the earth's core, mantle and crust, this live action video shot all over South Dakota looks at how the geologic forces of glaciation, erosion and uplift produced a varied topography in the state. It then takes a look at its geology. It investigates its sedimentary rocks and shows how they were formed. Computer animation will show students how rocks were deposited. It also looks at how the land was uplifted and discusses the formation of the Black Hills. It then looks at the affects that glaciers had on South Dakota. A great introduction to the state's Geography and Geology!
