geographic boundaries
Lines dividing regions
Geographic boundaries are lines or zones that define the limits of a territory, region, or jurisdiction.
Some follow natural features—rivers, mountain ranges, coastlines—while others are political constructs drawn on maps: The geographic boundaries of the district were redrawn after the census.
The term often appears in discussions of sovereignty, resource rights, or administrative divisions.
