Description: Produced in cooperation with the American Geological Institute. Shows a parallel between the constant flux of the atmosphere and the hydrosphere, and the deformation on and movement of the lithosphere. Points out that field evidence, confirmed by laboratory experiments, shows that underground rock can both break and flow at the same time, when under great pressure and high temperature.

Complete Record: , Produced in cooperation with the American Geological Institute. Shows a parallel between the constant flux of the atmosphere and the hydrosphere, and the deformation on and movement of the lithosphere. Points out that field evidence, confirmed by laboratory experiments, shows that underground rock can both break and flow at the same time, when under great pressure and high temperature., Examines the nature of rock, using laboratory experiments to show rocks simultaneously breaking and flowing when under great pressure and high temperature. Illustrates a parallel between the constant flux of the atmosphere and the hydrosphere and the deformation and movement of the lithosphere. Allows for the projector to be stopped to stimulate classroom discussion of a question presented and gives sample answers to the question when projection is resumed., NOTE: Two (or more) records have been merged together to create this data.
