Pământul își schimbă forma. Devine mai rotund și mai turtit în același timp. Cum este posibil • Newsweek România

Earth's shape is changing, becoming both rounder and flatter simultaneously due to polar uplift and equatorial subsidence. A study by geologist Christopher Kotsakis reveals that polar regions are rising faster while equatorial areas are sinking. This phenomenon is linked to ice melting, which reduces pressure on the crust, causing it to rise. However, the redistribution of mass from melting ice into oceans leads to a gravitational shape change, making the geoid flatter. These processes, while seemingly contradictory, are physically compatible and reflect different aspects of Earth's dynamics. The ongoing adjustments are influenced by both recent ice loss and historical glacial changes.
