Titan is like Earth with its rivers, lakes, and seas filled by rain, but as stated, this is liquid methane and ethane as opposed to liquid water on Earth. Like Earth, Titan also has sand dunes, but they are made of hydrocarbons instead of silicate-based substances. Also, much like Earth, Titan is known for having a seasonal liquid transport cycle, also known as the water cycle on Earth, linking atmosphere, land, and oceans.

Back in the 1980s I read a lot of science fiction weaving epic tales and describing alien landscapes. These days, I continue to read things which are weaving epic, and describing alien—but they are no longer fiction.
