Planetary Science Methane Lakes on Titan

Titan's methane lakes reveal an alien world with a unique hydrocarbon cycle shaping its surface

0

What role do Titan's methane lakes play in its atmospheric and surface processes?

They are part of a hydrocarbon cycle involving evaporation, cloud formation, and precipitation, similar to Earth's water cycle. They are frozen solid and do not interact with Titan's atmosphere. They are composed mainly of water and contribute to a water cycle like on Earth.
