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?").
