As a registered field geologist, I'm not skeptical about plate tectonics, but I think it's an oversimplification. The theory concentrates on the ocean basins and continental margins, and pretty much ignores what's happening within continents.

And the more you look at them, the more active continents seem to be with oceanic transform faults continuing through continents in many areas, slicing them up and moving them around.

But plate tectonic maps that show the continents as anything but blank areas are as rare as hen's teeth.

Plate tectonics is correct, but it barely scratches the surface of what's really going on...
