Why exactly can't the Antarctic plate be a stationary "frame" around the earth's perimeter? The Antarctic plate boundary is miles away from the Antarctic land. The boundary is in the oceans.
Well, the most obvious reason is that the earth is a globe and thus doesn't have a perimeter.
Given that you guys can't even create a map you can all agree on it's weird that you're so confident of where plate boundaries are.
I wonder why you randomly agree with the science of plate tectonics when you reject basically ever other aspect of modern science.
