You know, there was a book I had many years ago that pretty much predicted this. The gentleman was talking about how the crust behaves, and how it is not like you would expect molten rock to behave.
I will have to dig though my library to find it.
They are STILL predicting this.
In the Beginning: Compelling Evidence for Creation and the Flood (7th Edition)
This was the book. The author talked about it in depth.
