I can keep going on, we even have the Antarctic Plate, obviously when you do a projection onto two dimensions of a surface of a sphere the stuff on the bottom and the top look much bigger than they actually are, Antartica isn't this big relitive to say North America or South America, we just had to streach it out to fill up the rectangle. but that's the Antarctic Plate, North American Plate, and you can see that they're actually moving relative to each other, that's what these arrows are depicting.
