I would presume all rocky planets still have (residual) heat in the core from their formation - X hundred or thousand miles of rock would be an excellent insulator - and also build up heat due to friction from gravity dragging layers of rock of different density. (Io is an excellent example of that - it has active volcanoes because it is so close to Saturn and is subject to big gravitational forces as a result).
Also, a meteorite hitting any rocky planet would have exactly the same effect as on Earth - earthquakes! |

I am glad you said that Brix because I have never really bought into this theory that we have been told on (and I must say that this and a few books for the amateur) the science programs that the Earth still has a burning core because it has not cooled down yet. Would you say that it is gravity that is keeping it burning. Could magnetic fields from other planets also effect it. In my mind it is like a perpetual motion machine that runs on and on and the Earth will never cool down totally. Am I sounding really stupid because I am interested but really have no clue. |
