Mountains And Mountain-Building ProcessesStreaming Video - 2012
We think of mountains as eternal, but they are evidence of our planet's surface bending and buckling like cardboard. Examining Earth's mountain-building processes in detail, this program also studies the weathering, erosion, and mass wasting by which mountains are worn down. Viewers gain insight into the basic factors that underlie volcanic activity, the various types of geological faults, and the tectonic processes in which oceanic and lithospheric plates collide, separate, or slip past each other, resulting in dramatic physical changes. Eye-catching graphics as well as live-action footage from the Alps, Andes, Cascades, Rockies, and Himalayas help illustrate concepts.
