Glacier melting reshapes Earth
A recent study reveals that the Earth is experiencing gradual changes in its shape due to melting ice at the poles and the redistribution of water in the oceans. Between 1997 and 2015, the polar regions' elevation increased by up to 1 millimeter annually as a result of melting ice in Greenland and the North and South Poles. This reduces pressure on the Earth's crust, causing the poles to rise. Conversely, the moving water towards areas closer to the equator causes a slight decrease in the Earth's crust there, which slightly alters the planet's geometric shape, making it less flat. Although the Earth takes on a more rounded shape, the resulting redistribution of mass reshapes the gravitational field, confirming that the shape of the Earth is continually changing due to plate tectonics and climate changes.
