So really the United States could be upside down. But I wouldn't think that because all the pictures I see the USA is upright. Well upright in my definition of up. Does a pole have to be the top of the Earth? Or can the equator in the middle of the Atlantic Ocean be considered a TOP.

for a rotating spherical body like the earth, the poles are defined as where the axis of rotation intersects with the surface
