When looking down at earth from space, you would be able to see the shapes of continents and even, if you are aware of geological history, the way, for instance that Africa and South America fit together as they were once part of the same mega-continent. When living on the surface of the earth, as we most often experience it, one gets an entirely different perspective in which the individual contours of the land, vegetation, buildings, and coastlines look much larger and have different proportions relative to the viewer. Both perspectives are real and equally valid but in each, different information is revealed or becomes salient to the viewer/participant.
