Volcanology
Isostasy is the state of gravitational equilibrium between the Earth's crust and mantle, where the buoyancy of the crust balances the downward pull of gravity. This balance is crucial for understanding how the Earth's surface responds to forces like tectonic activity, erosion, and sediment deposition. It explains why continents sit at different elevations and how geological processes can lead to uplift or subsidence over time.
congrats on reading the definition of Isostasy. now let's actually learn it.
