#913: Core explain

[A cutaway diagram of the Earth, with colored layers including a labeled outer core and inner core.]

[A closeup of the stylized outer core, labeled “Turbulent molten metals at 30 million PSI” with turbulence lines, and of the inner core, labeled “moon-sized iron sphere.”]

[Cueball reading a book pulls legs up tight under office chair, peering downwards.]

[Caption below the frame:]
