Earth’s Internal Structure: Layers of the Planet Explained #3886983 (License: Personal Use)

This educational diagram presents two complementary views of Earth’s internal structure: a wedge-shaped cross-section on the left and a full spherical cutaway on the right. Labels A-E identify surface features and atmospheric layers, while numbers 1-9 denote subsurface layers including the crust, upper and lower mantle, transition zones, outer core, and solid inner core. The color gradient reflects increasing temperature and pressure with depth.

Used in earth science classrooms, online geology courses, and educational websites to teach planetary structure; matches user intent for learning or reviewing Earth’s composition and layering.
