A Volcanologist Dances on Lava

Run Time: 00:03:40

On the Big Island of Hawaii, volcanologist Dave Sherrod of the Hawaii Volcano Observatory, USGS, treads on the newest rock on the planet. He burns his shoes on the hottest part of the flow, but a few minutes later, the lava has cooled enough to stand on. Sherrod explains the difference between lava, which is molten rock that flows on the surface, and magma, which is molten rock under the surface. Featured Scientists: Keith Klepeis, Ph.D. and David Sherrod, Ph.D.
