INDIAN GEOGRAPHY

Detailed explanation-1: -However, the Earth is not a perfect sphere; it is an oblate spheroid, and has a smaller radius at the poles than at the equator.

Detailed explanation-2: -Its shape is an oblate spheroid. This just means that it flattens at the poles and widens out at the equator.” Earth bulges at the equator because of the centrifugal force during rotation. Like spinning a pizza, the mass pushes outwards and flattens out along the axis of rotation.

Detailed explanation-3: -Something that’s oblate is rounded, but instead of being a perfect sphere, it’s flattened slightly on the top and bottom. Although we imagine the Earth to be shaped like a basketball, it’s actually slightly oblate.

Detailed explanation-4: -A sphere that has a bulged-out centre and flattened poles is defined as an oblate spheroid. The equatorial region of the earth is bulged out and the polar regions are flattened due to the rotation of the earth, and this is why the earth is considered an oblate spheroid.
