High tide. That is where the tidal bulge is.
I do think Ancient Antarctica was situated in a different location from it's locations today because of continental drift, this is caused by the moving of the tectonic plates by the mantle which is under the Earth's crust due to the cooling and heating of magma (or lava, cant remember). this causes the plates to collide with each other, go in opposite ways or "swallow" one another (basically one plate goes under the other causing the one under to melt and reappear where two other plates are separating)
I have a question are you asking what are the molecules of a shark or something
Because everything is everything is in levels. Example: It starts with the cells then tissues the organs and so on and so on
