Earth's Interior Structure - Layers, Composition, and Mantle Convection #3271992 (License: Personal Use)

This scientifically accurate cross-section illustrates Earth’s four main layers-crust, mantle, outer core (liquid iron-nickel), and inner core (solid iron-nickel)-with white arrows indicating thermal convection currents in the mantle. These currents transfer heat from the core outward, driving the movement of tectonic plates and influencing volcanic activity, earthquakes, and mountain formation. The surface shows realistic continental outlines for geographic context.

Used in educational science websites, geology textbooks, and planetary science resources to explain Earth’s internal dynamics; targets students, educators, and curious learners seeking foundational knowledge about geophysics and Earth systems.
