=Regions: The Final Theme of the Five Themes=

There are three different types of regions: - taken from //Five Themes of Geography// by Matt Rosenberg (About.com)
 * **Formal regions** are those that are designated by official boundaries, such as cities, states, counties, and countries. For the most part, they are clearly indicated and publicly known.
 * **Functional regions** are defined by their connections. For example, the circulation area for a major city newspaper is the functional region of that paper. (This means that there must be a core that extends outward in terms of influence. That influence will diminish over distance. Thus, one could say that, for example, much of Gyeonggi-do is part of the "Seoul region".
 * **Vernacular regions** are perceived regions, such as "The South," "The Midwest," or the "Middle East;" they have no formal boundaries but are understood in our mental maps.
