Titan, Saturn's largest moon, has a unique geography with rivers, lakes, seas, and waves composed of liquid methane and ethane hydrocarbons due to extreme cold temperatures, making it unique in the solar system. The Cassini mission and Huygens lander confirmed the presence of these liquid bodies. Researchers from MIT, the U.
S. Geological Survey, and other institutions conducted a study published in Science Advances, using simulations to investigate the role of waves in shaping the shorelines of Titan's seas and lakes. The study identified four of Titan's seas where wave-driven erosion likely sculpted the shorelines, validating their simulations by comparing with Earth lakes eroded by waves.

Geologists believe that waves have shaped these large seas based on simulations, suggesting that erosion caused by waves may have sculpted the shores of Titan. While initial analysis suggested Titan's seas and lakes were fairly flat with minimal wave activity, some researchers observed roughness on the liquid surface, indicating the presence of waves.
Direct observations are necessary to confirm the erosion theory due to challenges posed by Titan's atmosphere, distance from the Sun, and seasonal variations. The researchers proposed three erosion scenarios for Titan's seas: no coastal erosion, erosion driven by waves, and uniform erosion c.
