Metamorphic Rocks—Why Rocks Bend And Fold, Part 2: Looking at the larger Region: Field and Maps

Run Time: 00:04:59

In this second of three video clips, geologist Keith Klepeis, of the University of Vermont, continues his investigation to explain how sedimentary rock from Clay Point, VT, has changed to folded metamorphic rock. What was the source of the heat and pressure that metamorphosed the rock at Clay Point? Klepeis connects the geological history of Clay Point to the larger region, specifically the Green Mountains and the Appalachians. Do the two colliding plates that formed these mountains also explain the immense pressure that caused the sedimentary rocks at Clay Point to bend and fold and change into metamorphic rock? Featured Scientists: Chuck Blay, Ph.D., Keith Klepeis, Ph.D., Andy Kurtz, Ph.D., Michael Manga, Ph.D., and David Sherrod, Ph.D.
