Which chemical in the atmosphere of titan (a moon of saturn) appears to play the same role that water plays on earth in producing “rain” and forming lakes and streams, at the temperature encountered on the moon?

Methane

Saturn is the least dense planet of the Solar system. It has about 62 moons. Saturn is known for its beautiful ring system. Titan is the largest moon. It has a very dense atmosphere and the only moon in the solar system to have so. Its atmosphere is composed of mostly Nitrogen, Methane and Hydrogen.
