If you had cared to answer an earlier question, we might have been able to make more progress in this area, so let's have another go. I asked: "Preearth, would I be right in thinking that your statements: "The single continent Pangaea covered 35% of the surface of the Earth." and, "Today, the continental crust covers only 35% of the globe" imply a belief that there was the same volume of continental crust present at both times? If so, you would need some evidence about the average thickness at both times."
I later asked you to explain why you think the volume is important (if you explained why you think it is important, I may be able to answer your question).
But you didn't bother to answer it, did you?
If you are going to insist that I answer your questions, perhaps you should answer mine (especially since that would help me answer yours)?
