So I'm arguing aganist a particularly ignorant creationist who believes that moutains (such as Everest) were created after the flood (therefore removing the ridiculous amount of needed water).
However, what he either doesn't understand or chooses to ignore is that compacting Everest into 6,000 or so years would require ridiculous plate movements.
I've calculated from sea level that plate movement would need to be around 5 (60 inches) feet a year to raise Everest to its current height over 6,000 years.
What I don't have down is the corrolating heat from such plate movement. Plates as we know move about a inch a year the mantle is estimed to be around 1120 C. So it would seem logical to me that a increase in plate movement requires a increase in mantle temperature. How much temperature increase would be required for a increase from 1 inch to 60 inches in plate movement in the mantle?
I've done a rough 1 inch = 1120 and 60 inch = x but that seems like a bad estimate given that the temperature is something like 66,200 C.
Can anyone help me out here?
