I just used the 12th planet illustration because it was handy. I think SOMETHING spanged into Earth and tore a Helluva hole where the Pacific is now. I’m thinking plate tectonics exist because the land masses are moving to cover up the hole. (Yeah, I know it’s a crust floating on magma.)
If the earth was revolving as it solidified, why do they keep showing Gondwana or whatever as one giant land mass on one side of the earth, then breaking apart? It seems to me it broke apart to cover the missing land mass torn out.
Or, on the other hand, all land masses were located roughly where the South Pole is today until after 650 Million years ago and have migrated since - according to most geologists. This makes the ‘hole’ just a void that has not been filled - like the smaller void in the Atlantic.
Why they were located there is an interesting question - was there a larger body which the Earth orbited and gravity pulled the land masses toward it - see the Saturn Myth.
