Answer:
Borders are imaginary lines that divide a nation, state, province or city from others. These dividing lines can be taken from geographic features, such as rivers, seas, lakes, mountains, etc .; or in geometric form, using lines as meridians and parallels; or for ethnic reasons, dividing populations based on languages, ethnic origin, etc.
Examples of each of these types of border are:
-Natural border between Argentina and Chile along the Andes Mountains, taking as the dividing line the highest point of the same.
-Geometric border between America and Canada on the west coast, taking the line of parallel 49 as division.
-Ethnic border between Pakistan and India, dividing both nations according to concepts of Islamic or Hindu religious affiliation.
People here in America are used to more personal space because it is not over populated. But in other countries with crowed houses and overpopulation you would not even be able to walk in your own space.
