Bill Nye The Science Guy: Rocks & Soil

Bill Nye discusses the forces that affect the surface of the Earth in Bill Nye the Science Guy: Rocks & Soil. He explains that any of these forces can be violent, as in earthquakes and volcano eruptions, while some transform the Earth over a long period of time. The Science Guy looks at the inner workings of the Earth, and tells how rocks break down to help form soil. Nye inserts his usual trademark humor and parody into the scientific discussion to create a fun learning atmosphere.
