i just realized that the ice on the south pole is so thick that it weight must be making a 5mile deep depression in the earth. that might explain why all continents are shaped like triangles pointing south. note that the south pole is colder than the north pole because the earths orbit is elliptical and the earth's axis is tilted. the north pole melts more and the south pole gets colder. but i never realized the impact of the south pole continuously accumulating snow on the surface till it forced its way into the earths crust and melts. maybe someone told me. but i didn't pay attention. its simple celestial geometry
