Why is earth called oblate spheroid?

Answer 1

Answer:

He included a proof that a rotating self-gravitating fluid body in equilibrium takes the form of an oblate ellipsoid of revolution (a spheroid).

Answer 2

Because the average shape of the earth is not a perfect sphere, but slightly flattened out due to its rotation - this shape is called an “oblate spheroid”. ...
