Because it's so cold here, these sounds aren't coming from the flowing water we see here on Earth, but a lighter liquid. Instead of water, what flows on Titan is a mixture of liquid methane and ethane. In the solar system, only the earth can allow the three states of water to coexist. We have liquid water, solid ice, and water molecules floating in the air. But on Titan, something else plays a similar role: methane and ethane. Some of the methane and ethane on this celestial body are in solid form, while others are gas or liquid. The water as we know it is cold enough to be as hard as steel in this place.
On Titan, there are oceans and lakes formed from lighter Image Manipulation Service liquids, methane and ethane. When these liquids evaporate, they reagglomerate to form rain and snow. The moon's weak gravity causes methane and ethane in the thick atmosphere to form huge snowflakes that slowly fall to the ground. Afterwards, some turn back to liquid, returning to lakes and oceans along with rivers and creeks. Titan is a place other than Earth that has this complex "water cycle", but in fact it is another substance that replaces water. But the strange thing is that the ocean on Titan has no ripples.
Radar images from Cassini showed that the oceans were almost smooth. On the surface of Lake Ontario (Ontario Lacus) in Titan's northern hemisphere, the undulating height is less than a few centimeters on the surface of the 100-meter-wide surface. This is believed to be because the liquid methane and ethane mixture is more viscous than water, and on this extremely cold planet, the winds are too weak to wrinkle the sea. Therefore, if you want to hold wind and wave sports on this satellite, you will definitely lose money.
