“…Organic materials, produced by long‐term photochemical processing of methane and nitrogen in the upper atmosphere, cover much of Titan (Barnes et al., 2008, 2011; Brossier et al., 2018; Clark et al., 2010; Krasnopolsky, 2009; Lavvas et al., 2008; Mackenzie et al., 2014; Soderblom et al., 2007; Solomonidou, Neish, et al., 2020; Solomonidou et al., 2018; Wilson & Atreya, 2004). Titan's equatorial zones are dominated by massive organic sand seas (Lopes et al., 2010; Lorenz, Wall, et al., 2006; Radebaugh et al., 2008; Rodriguez et al., 2014), whereas the mid‐latitudes are dominated by “undifferentiated plains”: patterns of wind deposition on Titan show that, for both northern and southern hemispheres, winds transport material from both the equatorial regions and high latitudes toward the mid‐latitudes (a belt at ∼35°), where materials are eventually concentrated and deposited as undifferentiated plains (Lopes et al., 2016; Malaska, Lopes, Hayes, et al., 2016; Solomonidou, Neish, et al., 2020). A variety of channel networks and fluvial valleys have been seen by both the Cassini orbiter and by the Huygens probe during its descent, suggesting that liquid hydrocarbons have flowed energetically across Titan's surface (Birch et al., 2016; Burr, Drummond, et al., 2013; Burr, Perron, et al., 2013; Burr et al., 2009; Langhans et al., 2012; Radebaugh et al., 2018).…”
