Just get hold of a good National Geographic Atlas of the World, which has a series of underwater maps in the back. Open it up and take a good look just to the west of Greenland, and you'll be able to see the exact outline, showing percisely where Greenland was one located on the Artic Ocean Floor! It's also very easy to see that at one point, not only the tip but the whole continent of Greenland rose up on end. When it started, it was in an eight o'clock position, and yet, rotating to the east as it came crashing down, it endid up in a four o'clock position as we yet find it today. The point is that all this happened - and I find it to be either evidence of that time when the mantle did significantly expand - or it must be something on the order of God's own little tiddley-wink.
