Question

Why is the shape of the earth described as an oblate spheroid?​

Answer 1

Sir Isaac Newton proposed that the Earth flattens at the poles because of rotational forces. As the Earth spins on its axis, the centrifugal force causes the Earth to bulge out at the equator. This is why the Earth is better modeled as an ellipsoid, which is a sphere slightly flattened at the poles.

Answer 2

Answer:

the earth appears to be perfect sphere, it is not so. The measurement of the earth at the equator and poles show that it has a slight bulge at the equator while it is slightly flattened at the poles. thus the word usedto describe the shape of the earth is oblate spheroid.
