I don't know, what you're trying to say.
But the Earth isn't neither a sphere nor a circle.
Earth is is more like a massive ball, that is bugled outwards at the
equator.
Yes, very close to an oblate spheroid.
The term 'sphere' and 'spheroid' belong to the surface of a ball and a
rotation ellipsoid.
It's not recommended to call a ball 'sphere', because a sphere has no
thickness.

Yes, the surface of a ball determines its shape.
