The Earth is an oblate spheroid and not a perfect sphere. This is because [CDS 2010] 1. the Earth has a rotational motion and the rotational speed increases as one goes from the Poles towards the Equator. 2. the Equator experiences greater gravitational pull from the Sun. 3. the intensity of sunlight received at the Equator is greater than that at the Poles.
