Question

What is the shape of the Earth?

Answer 1

The shape of the Earth is an oblate spheroid, meaning it is slightly flattened at the poles and bulging at the equator. The equatorial diameter is about 12,756 km, while the polar diameter is about 12,714 km. This shape is due to the centrifugal force caused by the Earth’s rotation. Thus, the Earth is not a perfect sphere but resembles more an orange in shape.
