Falsifying Plate Tectonics.
Watch this space.
Strike 1. (coming up) No mechanism.

I know properly this should belong in sci.geo.geology, but the best
they can do over there is show each other pebbles they collected at the
weekend, ..and swap stories about walks and pictures they took, so I'm
looking to broaden the reach. Bob Grumbine says there are people in
talk.o who know some geology, and I think the point should be of
interest to physics since if Plate Tectonics doesn't work, then what
does?

Repeat:- This thread is about how to falsify Plate Tectonics: No
sidetracks please.
