What is the shape of the Earth?

The Earth is not a perfect sphere; it is slightly flattened at the poles and bulging at the equator, making it an oblate spheroid. This shape occurs because the Earth’s rotation causes it to slightly stretch around the middle. The Equator is the widest part of the Earth, while the poles are a bit squished. This shape affects how gravity pulls and influences the Earth’s overall features like oceans and continents. The oblate spheroid shape is crucial for understanding the Earth’s rotation and climate patterns.
