Which type of boundary would most likely cause the greatest political problems? explain.

A geographic border is a spatial line or strip separating one geographic entity from another. A border can be either natural or artificial. It can be both visible (marked on the ground) and invisible.

Natural borders can consist of rivers, lakes, seas, mountains or any other visible geographical accident that serves as a point of separation between two geographical entities.

In turn, artificial boundaries are created by man, through conventions or treaties between these geographical entities, in order to place a geographical delimitation between two or more nations, provinces or geographical sub-entities. This type of borders can be visible or invisible, depending on whether they are walls, artificial channels or geographical parallels.

Generally, the borders that bring more conflicts between nations are artificial borders. Conflicts can arise both when determining the border line, and in the use of that border on a day-to-day basis (especially in the case of invisible borders).
