Largest gravity anomaly on earth.
The geoid (/ ˈ dʒ iː. ɔɪ d /) is the shape that the ocean surface would take under the influence of the gravity of Earth, including gravitational attraction and Earth's rotation, if other influences such as winds and tides were absent. This surface is extended through the continents (such as with very narrow hypothetical canals).According to Gauss, who first …
