Earth's Internal Structure: Crust, Mantle, Outer and Inner Core Explained #3468068 (License: Personal Use)

This scientifically accurate illustration depicts Earth’s four primary layers: the thin silicate crust, the thick viscous mantle, the liquid iron-nickel outer core generating Earth’s magnetic field, and the solid inner core under extreme pressure. Dynamic red-orange swirls represent convective currents in the mantle and outer core, crucial for plate tectonics and geomagnetism. The visible surface shows continents and oceans for geographic context.

Used in educational science pages, geology textbooks, and planetary science resources to explain Earth’s composition and internal dynamics; matches user intent for learning about planetary structure, geophysics, or earth sciences.
