QUESTION: 
Does Pluto have plates or earthquakes like the earth?

ANSWER from Marc Buie on 27th May 1996:
Well, I suppose that might be possible.  We don't really know about that
many planets and we've got a lot to learn yet.  However, if I had to guess
based on what we DO know, I'd say that Pluto probably doesn't have crustal
plates or earthquakes like we have on the Earth.  One of the things a
planet needs to have plate tectonics is a hot molten core with the crust
floating on top.  Pluto's core is probably completely frozen and there
would be no way for plates to form and move around.
