286K views · 4.8K reactions | The rapid deglaciation at the end of the last ice age triggered isostatic rebound, where Earth’s crust adjusts as glaciers retreat. This process shifts the crust’s distance from the planet’s center of gravity, creating disequilibrium. As an oblate spheroid, Earth’s surface adjusts to restore balance, leading to significant tectonic activity and compensatory changes over time. | The Randall Carlson | Facebook

Earth Layers and Isostasy by Katryn Wiese Isostasy, ideal theoretical balance of all large portions of Earth’s lithosphere as though they were floating on the denser underlying layer, the asthenosphere, a section of the upper mantle composed of weak, plastic rock that is about 110 km (70 miles) below the surface. Isostasy controls the regional elevations of continents and ocean floors in accordance with the densities of their underlying rocks. Imaginary columns of equal cross-sectional area that
