ok then back to my opriginal point
if the whole thing melts, and gets distributed and spread out through cracks in the earth, won’t it cool off instead of continuing to melt down to the center of the earth as one blob of overheated goo?
(hows that for techinical terms?)
The key to your question is cooling. There is a lot of ground water. Who can say EXACTLY what would occur. But really, once you’ve progressed that far, none of it is good.
