Earth's continental and oceanic domains exhibit dramatically different structural characteristics. Continents contain the highest exposed elevations, while oceans contain the deepest known depressions and largest continuous basins.
This paper examines those differences as observable structural expressions. Rather than focusing on tectonic origin, the analysis evaluates how extremes are distributed across continental and oceanic environments.
Mountain systems, plateaus, trenches, abyssal plains, and basin networks are compared as large-scale geological forms. The objective is to establish a descriptive framework for evaluating how structural extremes are organized globally.
The continental-oceanic distinction provides an important comparison layer for later investigations involving gradients, directional relationships, and extreme-value clustering.
This paper expands the Week 5 framework from individual extremes into domain-wide comparisons.
