Thinking about the Earth...and its many parts

There are many ways to divide up the planet geographically into conceptually digestible chunks. At a large scale, it's commonly done by continent or by region, but each of these can be done multiple ways (yes, even continents, for which 5, 6 or 7 can be the "correct" answer to "how many?"). What you see here will likely change over time as this portion of grows. In the meantime, the careful observer will note some gaping holes in the coverage here...this is very much a work scheduled to be in progress....
