Question

Give a geographical reason for the earth is not a perfect sphere.

Answer 1

The Earth is not a perfect sphere because it rotates on its axis. This rotation causes a centrifugal force that pushes the Earth's equator outward, resulting in a slight bulge at the equator and a flattening at the poles. This shape is known as an oblate spheroid. The centrifugal force from the Earth's rotation causes the equatorial region to be slightly wider than the distance from pole to pole, making the Earth an imperfect sphere.
