I’m not sure.
However, what we all know is that massive loads of ocean sediments were, at some time in our past, deposited upon the continents. In fact, using Rockworks software, Dr. Tim Clarey (geologist and hydrologist) has figured that 55 million cubic kilometers of ocean sediments (with some eroded sediments mixed in) lie upon the North American craton.
And it lies 1 to 2 miles thick, not only on our continent, but on other continents as well.
So, this is something we know–we don’t have to hypothesize about.
We also know a certain amount of hydrodynamic power was required to pick up this load (in addition to the billions of marine organisms) from the ocean and beach…then transport and deposit it across the continents (over six megasequences). In fact, scientists should be able to do the math on this–figuring the needed hydrodynamics.
Then, we need to ask ourselves, "So how would such hydrodynamics be produced? Would it be by slowly, slowly rising sea levels over millions of years, that v e r y gradually spill over onto the continents (as currently proposed by evolutionary scientists)?
Or, wouldn’t much stronger, more powerful hydrodynamics be required? And, wouldn’t plate tectonics provide the energetic waters that could provide such power?
Again, something we know: there are over 30,000 miles of subduction zones, indirectly resulting from the 45,000 miles of seafloor rifting that occurred. And we know that such subduction zones, among other things, would produce a series of powerful tsunamis.
