News of the long-lived and not unusual cloud on Mars associated with 21 km tall Olympus Mons has people commenting. This tweet by planetary scientist Dr. Tanya Harrison says

I don't understand the conspiracy theory contingent that's going off re: the clouds over Arsia Mons.

 

What possible reason would we have to hide volcanic eruptions on Mars? Heck, NASA has shared plenty of pics of volcanoes erupting on Io (shown here) & geysers on Enceladus!

(see the tweet for the video)

Why exactly is the feature on Io called a volcano, and the feature on Enceladus called a geyser? I understand they are substantially different, but I'm asking about how the geological classification works on bodies with different materials and temperatures than those on Earth.
