Cryovolcano is a cool word, literally and figuratively.  You hear about it a lot when talking about solar system moons like Enceladus, and it’s one of those words that would make a heck of a great Hollywood disaster movie title, like ‘Sharknado’ or ‘Armageddon.’ I do not, however, endorse either of those movies, they were both terrible.  At any rate, a real cryovolcano seems like an interesting thing.  It’s a volcano in the sense that it looks a little like a mountain and spews out material when the pressure builds from beneath the surface, but it’s not your traditional Earth-like volcano...
