All our concerns disappear just a few hundred feet below the surface of the earth. The variety of life, the interactions of wind, earth, and water, glorious rainforests, continents of ice, burned desert soil, all are confined to a tiny skin atop the 4000 mile deep depth of the earth. Today, we venture below the surface, deeper than the wells and experimental Mohorovičić discontinuity explorations, to get to the mantle, where the Earth is molten. In the unimaginably deep sea of liquid rock, the petty concerns of nations, rainforests, and glaciers burn off and are dispersed in to the underlying flow. There they push against the surface, breaking though rarely, but pushing the continents around like the skin on boiled milk. The surface, even the atmosphere, complex as it is, is not the story of the Earth.
