A massive spherical globe sliced in a clean editorial cross-section. A microscopic needle point representing the Kola borehole compared against the massive depth of the Earth's radius. Composition: medium shot, side-profile macro perspective, featuring Centered floating editorial composition with wide white margins on all sides. Scientific details: Proportional scaling of crustal depth vs total planetary radius (12.2 km vs 6,371 km), rendered purely through graphical proportions without numbers. Color palette: Warm ochre, burnt sienna, deep slate blue, charcoal ink outlines on off-white paper. The complete visual composition must sit comfortably inside the canvas with generous clean white/off-white negative space visible on the left, right, top, and bottom.
