ice water
There is no liquid water on Calisto. It does have a lot of ice on its surface, so it has frozen water.

Callisto is one of Jupiter's moons and it is the most heavily cratered object in the solar system. It has a very thin atmosphere composed mostly of carbon dioxide. Callisto's surface is icy and heavily marked by impact craters of various sizes.
No, there is no evidence to suggest that the moon Callisto has diamonds on its surface. Callisto is primarily composed of water ice and rock, and there is no known geological process that would lead to the formation of diamonds on this moon.
There is evidence to suggest that Callisto, one of Jupiter's moons, may have a subsurface ocean beneath its icy crust. This ocean is likely composed of liquid water and may be located tens of kilometers below the moon's surface. Further exploration and research are needed to confirm the presence of water on Callisto.
Yes
Callisto's terrain is characterized by impact craters, ancient valleys, and multi-ring structures. It has a heavily cratered surface with some areas showing evidence of tectonic activity and possible cryovolcanism. Overall, Callisto's terrain is one of the most heavily cratered among Jupiter's moons.
Callisto, one of Jupiter's moons, has a surface gravity of about 0.126 times that of Earth, or 1.235 m/s². This means that objects on Callisto weigh less than they would on Earth due to the weaker gravitational force.
I doubt it, Callisto is very cold and probably has more ice than volcanic activity. Based on its surface though, it once may have been hot enough for some volcanoes, but more likely pummeled by meteoric debris.
No, Callisto hasn't had any internally driven resurfacing within the past 3 billion years. It may have liquid water inside its core, but if it does it hasn't done anything to resurface the moon like we see with Europa.
Callisto's surface age is 4 billion years old.
