The Earth is often described as an oblate spheroid. This shape results from the rotation of the planet, causing it to bulge slightly at the equator and flatten at the poles. The concept of Earth's shape is essential in understanding various geographical and astronomical phenomena. The oblate spheroid shape affects gravity, climate patterns, and ocean currents. Furthermore, advances in satellite technology have provided precise measurements of the Earth's dimensions, confirming its shape and contributing to studies in fields such as geodesy, navigation, and Earth sciences.
