Not just Middle Earth. The Wheel of Time's map has moutains which are basically just convenient borders around the sides of the rectangle that aren't sea.

Middle-Earth actually has an excuse since its physical features were explicitly not created by natural forces.

I have read many explanations of the "with a 45 degree polarising filter between two polarising filters at 0 and 90 degrees, light gets through, but without it, none does" experiment. I don't *understand* it. As far as I can tell, this is one of the confusing things which apply to waves to general, quantum or not; and the best explanations are not in terms of observation of other quantum weirdness, but in terms of EM radiation being absorbed and retransmitted (albeit in a way that preserves some important properties). Can anyone explain this better?

I always took the Middle-Earth maps to be schematic in the way that medieval T-O maps of the world are schematic. These were not used for navigation; nautical charts and real-world-based maps coexisted with these. (Orbis terrarum or mappa mundi should land you loads of examples.) Modern fantasy fiction maps generally derive from that type of map, not from reality; they are intentionally stylized.

Any geologists writing blithely about Tolkien really ought to do a literature search first, where they will find "The Geology of Middle-earth" (1995) and other writings by the late William A.S. Sarjeant, a professor of geology at the University of Saskatchewan, who had no trouble producing a tectonic analysis of Middle-earth geology.
