Interior structure of the earth

In Class 11 Geography, this topic from the chapter “Interior of the Earth” explains how scientists understand the planet’s hidden layers. Students study the crust, mantle, and core, along with the differences between the inner and outer core. They explore how seismic waves, gravity, density, temperature, and pressure provide evidence about Earth’s composition and physical state. The topic also introduces major discontinuities that mark boundaries between layers and helps connect Earth’s internal structure with processes such as volcanism, earthquakes, and plate movement.
