Earth’s Internal Structure - Layers of the Planet Explained #3886979 (License: Personal Use)

This educational diagram illustrates Earth’s four primary layers: the thin outer crust, the thick silicate mantle, the molten iron-nickel outer core generating Earth’s magnetic field, and the solid inner core under extreme pressure. The glowing red center emphasizes the intense heat-up to 5,700 K-driving convection and plate tectonics. The continents and oceans on the surface provide geographic context for the subsurface structure.

Used in geoscience education, planetary science articles, and earth system explanations; ideal for users seeking foundational knowledge about Earth’s composition, geodynamics, or preparing for exams.
