Answer:
A globe is a model of the Earth that is used to avoid spatial distortions on the planet. The effort to fit a round object on a flat surface has warped world maps. Since the globe is round, it maintains its accuracy. The globe offers a precise scale of distance between places.
The physical map would show some features that make natural borders, such as rivers, shores, mountain ranges. Those features are then likely places for borders, since they're hard to attach and easy to defend, and the physical features explain why the border is where it is and not for example 5 km next to them
