Earth’s Internal Structure Diagram - Crust, Mantle, and Core Layers #163929 (License: Personal Use)

This scientific illustration depicts Earth’s internal composition, highlighting four primary layers: the thin outer crust (green landmasses), thick silicate mantle, liquid iron-nickel outer core, and solid iron-nickel inner core. Depth scales indicate the crust extends ~1,700 miles deep, the mantle to ~4,300 miles, and the core reaches the center at ~7,900 miles. The diagram integrates geographic surface features with geophysical layering for educational clarity.

Used in earth science education, geology textbooks, and science websites to explain planetary structure; targets students, educators, and curious learners seeking foundational knowledge of Earth’s interior.
