Well there's your first problem....you're trying to get information on geology from "christiananswers", which is the equivalent of relying on the Geological Society of America for information on Christianity. Funny how folks like you would immediately recognize the absurdity of the latter, but are completely oblivious when it comes to the former.
Hang on a sec.....aren't you creationists always going on and on about how close-minded scientists are, how they're all about maintaining "dogma", and they persecute anyone who deviates even a little from the norm? Yet here you are now citing an example of scientists adjusting their models and explanations, even to the point of agreeing with a creationist!
Your creationist talking points are self-contradictory.
Turns out your source is just plain lying (and by extension, so are you).
Coe and Prevot (note the spelling) published an article in 1989 titled "Evidence suggesting extremely rapid field variation during a magnetic reversal". Note the title, and how they specifically wrote about rapid
field variation, not rapid reversal. There's a bit more to this (and it doesn't help the creationists), so if anyone is interested I can provide some resources.
Again, you and your source are not telling the truth, this time lying by omission. Baumgardner did indeed do some modeling of the sort of rapid tectonic movements that would be required for the Biblical flood. However, there was just a slight problem,
as Baumgardner stated himself in his creationist article (PDF)....
"Estimates for the present mantle viscosity make tectonic velocities greater than a few centimeters per year implausible. It appears almost essential to conclude the average mantle viscosity during the Flood and probably for many centuries afterward was several orders of magnitude lower than present to allow the large displacements of the continental blocks to their present positions...These observations all point to the need to remove large amounts of heat from extensive bodies of rock in the earth in order to account for the geological change proposed for the Flood. It is the author’s conclusion that this cannot happen within the framework of time-invariant physics."
And just in case you didn't catch the significance of that last bit about "this doesn't work within the laws of physics", Baumgardner sums it up at the end...
"Finally, it seems evident that the Flood catastrophe cannot be understood or modeled in terms of time-invariant laws of nature. Intervention by God in the natural order during and after the catastrophe appears to be a logical necessity. Manifestations of the intervention appear to include an enhanced rate of nuclear decay during the event and a loss of thermal energy afterward."
IOW, none of this works without massive miracles. Funny how neither you nor your source bothered to mention that little fact. But then, that's to be expected given how it's simply impossible to advocate creationism in an honest manner.
But I think what astonishes and fascinates me the most is how folks like you just don't care. Here it's been made abundantly clear that your source is lying, but I guarantee it won't phase you one bit, nor will it cause you to be more careful in the future. Accuracy and honesty don't seem to be qualities that are valued in creationist circles. The only thing that matters is supporting the Bible at all costs.
