Ohhhhh yes that’s it. It was also so much more movement than I was expecting! I was expecting us to go from pangea glob to continents and then some shifty shifty but man those tectonics were BUSY.
Lots and lots of convection in that mantle.
Pangaea is only the most recent supercontinent, and therefore the most known. there are believed to be several more iterations in this cycle of combining and breaking up large landmasses.
