This is the real shape of the Earth - the geoid. The geoid is the equipotential surface of the Earth's gravity field (level surface), approximately coinciding with the average water level of the World Ocean in an undisturbed state and conditionally continued under the continents. It differs somewhat from the globe from the store. | Jock Williams Meteorologist

The mysterious gravity hole in the Indian Ocean has puzzled scientists for decades. This massive gravitational anomaly, known as the Indian Ocean Geoid Low, is a vast region where gravity is significantly weaker than anywhere else on Earth. | The Brain Maze
