Popular culture often refers to earth as a rock. Jimi Hendrix's guitar instrumental 'Third Stone From The Sun', a 1990's TV sitcom titled 'Third Rock', and famed neuroscientist, psychoanalyst, psychonaut, philosopher, writer and inventor Dr John C. Lilly, called earth a mudball. But the earth is far more complex and dynamic than a rock. A rock is typically uniform of substance and displays little or no activity. Earth is round and its crust has volcanic activity, geysers, and mineral veins. together these features form a complex layer of mixed geomorphology, geology, and topography. A thin layer of water has its own complex dynamics. The earth itself as an object extends beyond its surface, holding an atmosphere by gravity. A megnetic field, generated by earths core, extends far beyond the atmosphere. And somehow over billions of years life evolved on earth and vegetation carpeted the landmasses. Out of life came intelligence.
Earth is not a rock
"The Earth is not a big rock, infested with living organisms, any more than your skeleton is bones infested with cells. The Earth is geological, yes, but this geological entity grows people.... we are; I think, quite urgently, in need of coming to feel that we are the eternal universe, each one of us." Alan Watts, philosopher
what is the main difference determining properties and chsrscteristics between a rock and a planet or asteroid? MASS!
