Interior of the Earth
पृथ्वी का आंतरिक भाग
In Class 11 Geography, the chapter “Interior of the Earth” examines how scientists infer the Earth’s internal structure through indirect evidence such as seismic waves, meteorites, and volcanic activity. It explains the major layers—the crust, mantle, and core—their composition and physical properties, and how temperature, pressure, and density change with depth. The chapter also introduces the discontinuities that separate these layers and their significance in understanding Earth’s structure.
