What makes Earth Float on Lava? Isostasy | Geography for UPSC | Kapil Bhardwaj | UPSC Preparation

Isostasy is a geological concept that describes the balance and equilibrium of Earth's lithosphere on the denser, semi-fluid asthenosphere beneath it. It explains how the Earth's crust floats on the more fluid layer due to variations in density and thickness. When mountains or ice sheets form, the crust becomes buoyant and rises, while erosion or ice melting causes the crust to sink back into the asthenosphere. Isostasy plays a crucial role in shaping the Earth's surface, determining the elevation of landforms, and maintaining the dynamic equilibrium of the planet's lithosphere over geological timescales. 🔴Geography for UPSC CSE 2024 by Kapil sir    • UPSC Geography Lectures by Kapil Bhardwaj ...   NIRNAY IAS : Comprehensive coaching for IAS.
