Antarctic Gravity Hole Explained By Deep Earth Movements
Gravity’s strength is not uniform across Earth’s surface, with the weakest pull found beneath Antarctica due to slow shifts of deep mantle rock over millions of years. This “gravity hole” causes sea levels to be measurably lower around the continent and coincides with major shifts in Antarctica’s climate, including the onset of glaciation. Researchers used earthquake data and computer models to map this anomaly and reconstruct its evolution, suggesting a potential link between Earth’s interior, gravity, and the growth of ice sheets.
