Which of these is responsible for the variable way that we see Saturn’s rings on Earth?
The Earth's relative position to the Sun.
The brightness of Jupiter's reflection
The tilt of Saturn on its axis.
Saturn's retrograde rotation

water can exist on the surface if it contains salt
liquids can only exist temporarily on the surface
methane & ethane gases which have a low liquidation point

A moon of Jupiter that has the potential to support alien life. It has geysers which means that it could have an underground liquid ocean that is salty.
Ganymede
Titan
Europa
Perseverance rover
The largest moon of Saturn and is the only moon in our solar system that has an atmosphere. It has rivers, lakes, seas, and may contain oceans (the liquid in these places is not water, but another type of liquid).
Ganymede
Titan
Europa
Perseverance rover
A moon of Jupiter. It is the largest moon in our solar system. It is the only moon to have a magnetic field (this would protect life from radiation). This moon could have ice and liquid water below its surface that could be an ocean.
