Earth’s Internal Structure: Crust, Mantle, Core Explained #3380213 (License: Personal Use)

This scientifically accurate cross-section illustrates Earth’s four primary layers: the thin silicate crust (5-70 km thick), the viscous mantle (~2,900 km thick), the molten iron-nickel outer core generating Earth’s magnetic field, and the solid inner core under extreme pressure. The glowing red and yellow hues represent intense heat, ranging from ~1,000°C in the upper mantle to over 5,000°C at the center. Seismic data and geophysical modeling support this structure, essential for understanding volcanism, earthquakes, and geomagnetism.

Used in educational websites, geoscience textbooks, and museum exhibits to visualize planetary structure; matches user intent for learning about Earth science, geology fundamentals, or preparing classroom materials.
