Question about the shape of the earth

[paulojomaje]

Why is the earth not perfectly round

[phinds]

if you spin a ball that is not perfectly rigid, it bulges outward slightly at the spin equator. If it were made of jello, it would bulge out quite a lot.

[TheMadMonk]

The distribution of mass on earth is not constant, altering the shape of the earth.
