Oh, while we're on the subject of Coriolis, hurricanes (or, more to the point, their rotation) proves that the world is not flat. Just in case anyone here was in any doubt...
A flat earth that is rotating would have hurricanes all rotating in the same direction. Well, unless by "flat earth" they mean flat like a coin, with people living on both sides. But they obviously don't argue in favour of that model, because we can travel to Australia without having to go round an edge.
