If dustypuss wanted Quora to answer her question she might have asked it on there?

Some planets like Jupiter and Saturn are just gas, but the other planets have caves, mountain ranges and so on.

Interesting. Yes I guess they could have those lava tube type "caves" Not that I'm any expert.

But to me a "proper" cave is one where the sea/ocean (or other water (or it's equivalent) of some kind) has worn away rock/mineral to produce it.

Maybe Titan has such things eroded by its methane lakes ?
