geographical boundaries
Lines dividing regions
Geographical boundaries are lines or features that mark the edges of territories, regions, or jurisdictions.
They may follow natural features like rivers, mountain ranges, or coastlines, or they may be arbitrary lines drawn on maps: The Rio Grande forms the geographical boundary between Texas and Mexico.
Political borders, property lines, and administrative districts all represent geographical boundaries.
The term distinguishes physical or mapped divisions from abstract ones like cultural or linguistic boundaries.
