GENERAL KNOWLEDGE

Detailed explanation-1: -Even though our planet is a sphere, it is not a perfect sphere. Because of the force caused when Earth rotates, the North and South Poles are slightly flat. Earth’s rotation, wobbly motion and other forces are making the planet change shape very slowly, but it is still round.

Detailed explanation-2: -Answer: (a) Earth is slightly flattened at the North and South Poles, and bulges in the middle. The shape of the Earth is described as a ‘geoid’, that is, ‘an Earth-like shape’.

Detailed explanation-3: -The Earth is an oblate spheroid. The shape of the Earth is affected by factors such as gravity, stress, and density.
