The crust extends over the entire Earth, averaging 50 km (164,000 ft) on land and 20 km (65615 ft). So a much, much greater mass of crust than water. And the energy required to quickly move and then slow the blocks of crust would boil the oceans, when it was released as heat. Energy isn't magically created and destroyed; it's always converted to another form of energy. So the energy required to accelerate and slow the crust would be released as frictional heat.
And the oceans would boil. Unless it happened over tens of millions of years so the head could be slowly removed by conduction.
Which is why most Bible scholars see that division as being a division into different people with different languages and cultures.
Sorry, I guess we are both just going to keep repeating the same things to each other.
It is only theory/opinion that they would boil, they don't have definite there-then eye-witness proof.
And I've already said it may have been during the flood so there were not just "oceans" during the flood.
They have not drilled right through to the mantle etc so they oly know what surface and mining/excavation and drill cores they have done at spots around the world. They don't know for sure everything below the land and below the seas.
Even continental "drift" is only theory though there does seem good evidences for the continent having previously been one landmass.
The bible does not support any 10s of millions of years anywhere between the Fall and the present, and Genesis 1-2 seems to imply only one landmass. Nor is there indisputable proofs of millions of years in natural history and geology.
The Andes were pushed up suddenly and quickly with the lifetime of humans and civilisation. Even if one pushed humans/civilisation back intead of bringing the Andes movement forward, it still happened suddenly/quickly.
We also only know the post-flood world as we see it now and as recroded in what few records in the last 4000 or so years.
Moreover there are evidences for the Flood maybe having been during the transition between the Mesozoic/Cretaceous and Cenozoic, since there were on seasons before then and seasons are first mentioned after then, and Genesis implies axial tilt during the flood because it first mentions "summer and winter" just after the Flood.
I'm not a physicist unfortunately though I have some interest and ability in it. But my impression is that not all laws or facts or truths of physics & the universe are necessarily definitely certain and some people have some alternative interesting scenarios/theories.
I have already said the shift(s) happened either *during the Flood* or during Peleg division (question marked) or during Atlantis sinking event.
They have to provide more proof that "earth" can refer to people/languages. More proof of how animals and plants got to locations all around the world after the flood.
I do agree the the division in days of Peleg might not be continental shift, but it is not definite, and the point of the replies was only that the flood was surely global if there was only one landmass until the start of the Flood.
Revelation? says all the islands and mountains will flee or be leveled, so a reverse continental shift may be coming in future. I'm not sure it says anything about boiling seas there though some other verses speak of 1/3rd of all fish dying.
