Sand production mechanisms. Four different proposed pathways for the production of 300-micron saltatable organic particles on Titan. In the ‘bottom-up’ approach, individual haze particles fuse together over time by sintering or flocculation. In the ‘top-down’ approaches the 1-micron haze particles first form much larger rocks by either lithification or dissolution and precipitation before being broken down into sand-sized particles.
