HI FRIEND
Sir Isaac Newton was the first one proposed that Earth was not perfectly round. He suggested it was an oblate spheroid. A sphere that is squashed at its poles and swollen at the equator.
He was correct and, because of this bulge, the distance from Earth's center to sea level is roughly 21 kilometers greater at the equator than at the poles.
Earth's shape also changes over time due to a menagerie of other dynamic factors. Mass shifts around inside the planet, altering those gravitational anomalies. Mountains and valleys emerge and disappear due to plate tectonics. Occasionally meteors crater the surface. And the gravitational pull of the moon and sun not only cause ocean and atmospheric tides but earth tides as well.
