What is the shape of the Earth?

Solution (By Examveda Team)

Geoid is the shape of the Earth. There are many reasons why the geoid isn't a sphere. First and foremost, the Earth itself isn't a sphere. It is closer to an ellipsoid, being flattened at the poles by the centrifugal force of its own rotation. But the planet isn't an ellipsoid either, because of topography.
