Six-Ridge Tetrahedral Globe:
"As we take a close-up view of our little Spaceship Earth we see that the three-quarters of it which is covered with water has a greatest depth of about six miles, which is about the same as the six-mile altitude of its greatest dry land mountain peaks. We find that these ten-mile maximum variations of the spherical Spaceship Earth’s 8,000-mile diameter are comparatively negligible. If we are looking at a 12-inch diameter globe, the distance between the outermost mountain peak and the innermost ocean depth is only 1/50th of an inch, which visually is an almost undetectable amount. As we look at a 12-inch globe, the thickness of the ink with which an ocean is depicted is deeper in proportion to the globe than in the real Earth globe’s ocean depth in respect to its diameter.
“Three major mountain ridges of the Spaceship Earth converge in the Antarctic continent. From the South Pole one runs northwardly in the high continental plateau of Africa, and thence into Europe culminating as the Alps. A second ridge runs northwardly under water and emerges as Australia Malaysia, and later as Indo-China. A third ridge consists of South America’s Andes which runs northward through Central America to terminate”
