The Nature of Things

The Upper Mantle Project (2x6)

: 08, 1962

Program guest J. Tuzo Wilson, Professor of Physics, University of Toronto, and host Lister Sinclair look at a Canadian plan to survey that part of the earth laying immediately under the crust in an effort to learn more about the earth's formation, its landscapes and weather. Also, they show why a piece of lava is unreliable evidence of what lies beneath the earth's surface.
