How Solid Is Rock?
- 1968 ----- color ----- 21 min ----- 16mm
- The earth, when considered over the long span of geologic time, behaves much like a soft ball. Establishes a parallel between the constant flux of the atmosphere and hydrosphere and the deformation and movement of the lithosphere. Field evidence, confirmed by laboratory experiments, shows that underground rock can both break and flow, even at the same time, when under great pressure and high temperature.
