Surprisingly, plate tectonics is a relatively new field of study and wasn't accepted until 1965, and before that, there was a nebulous contiential drift theory proposed in the 1910s. And of course, curriculums and books lagged behind that.

That also means that Geologists have been reverse engineering plate tectonics since then and there are several diverging theories as to where things were at different geoglical eras after going back far enough.

Here's a bunch of nerdy geology videos, if you like that kind of thing.
