Earth’s Internal Structure: Crust, Mantle, Core Layers Explained #163935 (License: Personal Use)

This scientific illustration depicts Earth’s internal structure in cross-section, highlighting major layers: the oceanic and continental crust, lithosphere, asthenosphere, upper and lower mantle, liquid outer core, and solid inner core. Key boundaries such as the Mohorovičić Discontinuity (M-M) and depth measurements (e.g., 2900 km to the core-mantle boundary, 6371 km total radius) are clearly annotated. The inset zooms into the crustal layers for comparative thickness.

Used in educational science websites, geology textbooks, and planetary science resources to explain Earth’s composition; matches user intent for learning about plate tectonics, seismic studies, or Earth system science.
