Part 5 Continental Drift -- Understanding the Earth
Host; Dr. David Pearson.
Today, continental theory is superseded by plate tectonics.
Continental drift treated only the continents as jigsaw puzzle whereas plate tectonics treats the continents, oceans and the earth's crust as pieces of jigsaw puzzle.
These segments are a flashback to part of the development of the current theory
•Meeting in 1964 London, England
•Showing connecting continents on a map
•500 fathom line true edge of continent
•Joining the southern hemispheres continents together
•Professor Hurley from MIT looked at Cratons when reasoning continental drift
•Matching of the strata and ages, good way of seeing how the continents where joined
