This is the big cycle. The cycle that has been running on lithosphere –which is known as plate tectonics- is the small cycle. The running of the big cycle, make the small cycle to run. When the running of the big cycle will stop (when the fuel of the earth run out), the small cycle will stop. This means the continents will not move any more. This is the case of Mars, where no big cycle running, no plate tectonics taking place and no life. | |

We know many differentiated bodies, but not all have the strong orogeny that continents would require; and while some have tectonics, only one example is known to have plate tectonics. And life is, of course, an open question. | |
