Question

Two factors responsible for the shape of the Earth​

Answer 1

The earth is not a sphere. It is an oblate spheroid. The flattening in this image is exaggerated in order to make the earth's non-spherical shape obvious. The bulging at the equator is caused by the centrifugal force due to the spinning motion.

Answer 2

The most significant deviation from the standard value of g is a result of Earth's rotation. As Earth spins, its shape is slightly flattened into an ellipsoid, so that there is a greater distance between the centre of Earth and the surface at the equator, than the centre of Earth and the surface at the poles.
