Catastrophic Tectonic Plate "Sprint" and Rates of Helium Diffusion Used to Date Rock Samples

Here is a video the 8th graders and 6th graders watched or will watch in class about the possibility that tectonic plates could have "sprinted" during the flood from a supercontinent to our separated continents.  The video also discussed the problems with radioisotope dating vs. dating via measuring the diffusion of helium atoms in a rock sample.

Dr. Baumgardner is a Ph.D. in geophysics and he is also a Creationist.  He developed a software program called Terra that models the interactions between the mantle and the crust of the Earth that secular scientists around the world use.

This video contains college-level concepts, but I thought it was fascinating!
