Earth is filled with a variety of land formations -- from mountains to valleys, canyons to plains. But what's the difference between a folded and a block mountain? A mesa and a butte? A bay and a peninsula? In Land Formations, students learn the answers to these and other questions as they examine how forces such as weathering and continental drift have impacted the rise and fall of land on Earth. A fun, hands-on demonstration showcases the effects of the seafloor spreading at mid-ocean ridges and sinking in deep trenches, while a visit to the dramatic Devil's Postpile illustrates how the forces of nature can shape and define the land.
