Default Moments of Inertia and the Shape of Continents and Landmasses on Earth

Then, if you consider the shapes of the continents, North-America,
South-America, Africa and Asia have more or less triangular shape.
Europe could fit in the triangle of Asia and Australia is what I think
forming a triangle.
So, the triangular continents all have it's center of gravity at the
part of the continent facing the north-pole.
NB: I didn't much take account of mountains, I just considered the
flat surface of the continents as seen on Google Maps and other maps,
also trying to keep in mind the projection-method used on those maps.
(spherish Earth -- flat rectangle map, perhaps Mercator is involved)


What really bothers me is the fact of those triangular shapes of most
of the continents and why they all have the same orientation.
Nobody could explain that yet.
And that's why I thought some enormious centrifugal forces are
involved.
