Earth’s Internal Structure Diagram - Crust, Mantle, Core Layers Explained #3738071 (License: Personal Use)

This educational diagram illustrates Earth’s concentric layers, including the thin oceanic and thicker continental crust, the rigid lithosphere atop the ductile upper mantle, the lower mantle extending to 2,900 km, the liquid outer core at 5,100 km, and the solid inner core at Earth’s center (6,378 km radius). Depth annotations and labeled cross-sections clarify compositional and mechanical boundaries critical to understanding plate tectonics and geodynamics.

Used in earth science textbooks, online geology courses, museum exhibits, and K-12 STEM resources to visualize planetary interior structure; matches user intent for learning or teaching Earth’s composition and layering.
