Earth's Layers Explained: Crust, Mantle, Outer Core & Inner Core #3738088 (License: Personal Use)

This educational diagram depicts Earth’s concentric layers: the thin outer crust (green), the thick silicate mantle (red-orange), the liquid iron-nickel outer core (orange), and the solid iron-nickel inner core (yellow). Each layer is labeled with distinct colors and proportional thicknesses to aid visual learning in earth science contexts. The illustration emphasizes compositional and physical state differences critical to understanding geodynamics and plate tectonics.

Used in educational websites, science curricula, and geology resources to explain planetary structure; targets students, teachers, and curious learners seeking foundational knowledge about Earth’s interior.
