I don’t know exactly what that OU programme really said, but it sounds to me as though something got lost in the translation. We have fairly complete maps of world tectonic plate boundaries by now, including where there is subduction and where there is sliding or buckling, and I don’t notice anything that looks like concentric circles.

As for prediction or reconstruction of continental boundaries, we have some pretty impressive histories and predictions already, based on both geology and physical models. There have been animated displays on the WWW for a long time. If you google “Continental drift animation” you should find some excellent examples, eg: http://jan.ucc.nau.edu/~rcb7/global_history.html

Why? Basically because there is heat being generated within the planet by radioactive decay, and this causes convection currents. If you want to get the idea, try watching the surface of a simmering soup or gravy with some drifting fat, but not enough to cover the surface. Watch how the patches of fat drift, collide, and break up. Rock behaves something like that on the surface of the planet and for some thousands of km down.
