Check this out, from creation.com:
"Whether that particular figure is right or not, there is most likely a severe heat budget issue for any purely natural explanation of what happened during the Flood.1 As such, there is no simple scientific answer to this issue. Indeed, there may not be one. However, this need not be problematic. Why? First, the biblical evidence casts considerable doubt on any notion that Noah’s Flood was a purely natural event." -Shaun Doyle, creation ministries international.
Supernatural events aka miracles. In this case, specifically in association with plate tectonics and the heat they generate while moving around.
From Baumgardner at global flood.org:
"My own view is that it is utterly impossible within the framework of the laws of physics we know to account for (1) the accelerated nuclear decay (most of which occurs in the continental crust and not the mantle), (2) the removal of the huge amount of heat released by such accelerated decay (which would vaporize that crust if not quickly removed), or (3) the removal of heat required to cool the oceanic lithosphere to its current temperature at the end of the Flood cataclysm. It is my own settled conclusion that the miraculous is unavoidably required to account for all three of these phenomena."
Larry Vardiman from the institute of creation research:
For example, if most of the radioactive decay implied by fission tracks or quantities of daughter products occurred over the year of the Flood, the amount of heat generated may have been sufficient to vaporize all the waters of the oceans and melt portions of the earth's crust, given present conditions. (Vardiman 2000: 8)
Valdiman et al (a paper including all the YEC big shots):
"So, the basic hypothesis of this minority view within the RATE group called for supernatural intervention by God to accelerate the decay rate " "He employed some supernatural process which does not occur today or cannot be detected. However, He commonly uses natural law to do His work on earth, and so we believe it may be possible to discover how He did it." "God supernaturally protected Noah and his entourage by rapidly removing the large amount of heat that was produced by some unknown mechanism""
All of these events were supernatural, if not
in kind, at least in terms of energetics and speed. So, it seems possible to us that some, even most, of the daughter products we observe could Have been formed during the early Creation week"

Russel Humphreys:
"A simple calculation shows that crustal rocks with their present amount of radioactivity would melt many times over if decay rates were accelerated. However, I would like to emphasize here that all creationist Creation or Flood models I know of have serious problems with heat disposal. (Baumgardner 1986: 211, cited in Humphreys 2000: 369 –70)*
This is like the pinnacle of YEC geology right here. It's the best of the best on their end. And this is what they say themselves in their own words. Erase all physics, replace with the word "miracle".
YEC scientists basically fall into two camps. Camp A. It was a miracle or Camp B: we don't know.
And as an OEC, I would say, Camp A. Is 100% correct that if they want this to fly, they'd need miracles to get past the physics.
Same with the speed of light topic, same with radiometric dating, same with molecular clocks and hyper mutation rates. Etc.
