Title: How are cryovolcanoes different to magma volcanoes?
Post by: thedoc on 11/07/2016 11:55:48
I heard recently that there may be cryovolcanoes on Pluto.  This was explained to me as ice-volcanoes where instead of magma, molten rock, there is water. But what is the difference between ice and rock? Ice is frozen water.... Rock is frozen magma. Right? Is there a fundamental difference?

Exploding plumes of material (a volcano) relies on material which is heated sufficiently to turn into a liquid and/or gas, but then cools down into a solid, close to the source.

Farther from the Sun, it gets much colder, and different substances can be in this solid/liquid/gas zone.

So the main difference between volcanoes and cryovolcanoes is how hot (or cold) the liquid is.
Look for volcanoes as "tectonic" or "cryovolcano" here: http://en.wikipedia.org/wiki/List_of_tallest_mountains_in_the_Solar_System
