Earth’s Internal Structure: Layers of the Planet Explained #3741403 (License: Personal Use)

This infographic illustrates Earth’s concentric layers: the brittle continental and oceanic crust, the thick silicate mantle divided into upper and lower sections, the liquid iron-nickel outer core generating Earth’s magnetic field, and the solid inner core under extreme pressure. Each layer is distinguished by composition, density, and physical state, inferred primarily from seismic wave behavior.

Used in educational science pages, geology textbooks, and planetary science resources to help students and general audiences visualize Earth’s internal composition; matches user intent for learning about plate tectonics, geophysics, or earth science fundamentals.
