Get this: according to Plate Tectonics mythology, Earth is the only planet in the universe with subduction zones.
Why does plate tectonics occur only on Earth?
Abstract. Plate tectonics [allegedly] governs the topography and motions of the surface of Earth, and the loss of heat from Earth's interior, but appears to be found uniquely on Earth in the Solar System. Why does plate tectonics occur only on Earth? This is one of the major questions in earth and planetary sciences research, and raises a wide range of related questionsUT Dallas Geosciences Faculty Profile: Robert Stern
“Earth is the only planet with plate tectonics. That means it’s special in space, and it’s probably special in time, too. There must have been a time when the Earth didn’t have plate tectonics. The Earth had a very different tectonic, geologic style. There were no mid-ocean ridges with continents moving apart. There were no subduction zones where oceanic crust would have been going down,” Stern explained.LOL. Wow they are really desperate now.
