  Lakes on Saturn's moon Titan can stratify like those on Earth

  September 30, 2020 8:23 IST

  Lakes on Saturn's moon - Titan - composed of methane, ethane, and nitrogen rather than water, experience density-driven stratification, forming layers similar to lakes on Earth. However, whereas lakes on Earth stratify in response to temperature, Titan's lakes stratify solely due to the strange chemical interactions between its surface liquids and atmosphere, says a paper by Planetary Science Institute Research Scientist Jordan Steckloff.
