Earth’s Internal Structure: Crust, Mantle, Outer Core, and Inner Core #1908629 (License: Personal Use)

This educational diagram depicts Earth’s concentric layers: the rocky crust (thin outer shell), the thick silicate mantle (partially molten), the liquid iron-nickel outer core (generating Earth’s magnetic field), and the solid iron-nickel inner core (extremely hot under immense pressure). Colors distinguish composition and physical state, aiding comprehension of planetary formation and geophysical processes.

Used in educational websites, science textbooks, and geology resources to explain Earth’s structure; matches user intent for learning basic earth science, preparing for exams, or teaching K-12/college students.
