Earth's Northern and Southern Hemispheres exhibit substantially different distributions of continents, ocean basins, mountain systems, sedimentary basins, and polar environments. These differences provide an opportunity to evaluate large-scale geological organization using measurable planetary constraints.
This paper compares continental concentration, ocean-basin coverage, elevation distribution, basin occurrence, and structural continuity across both hemispheres.
Reference regions include North America, Europe, Asia, Greenland, Antarctica, South America, southern Africa, Australia, and the Southern Ocean.
Observable constraints include continental surface area, average elevation, basin frequency, structural clustering, and ocean-to-land ratios.
The objective is to determine whether hemispheric-scale organization provides useful comparative context for understanding planetary geological distribution.
This framework provides a globally measurable baseline for future Earth-system comparisons involving gradients, basin networks, and structural hierarchy.
