Evolution of the Atmosphere<br />
• Methane (CH 4 ) Is Broken Down by Electrons and Ultraviolet<br />
Photons<br />
• Some Hydrogen Escapes to Space Enriching Deuterium on Titan<br />
• Evidence Shows There Is a High Abundance of CH 3 D Methane<br />
• “Left-Over” Carbon Must Be Removed from the System to Remain<br />
in Balance<br />
• Ethane (C 2 H 6 ) Is the Most Abundant End Product<br />
• Titan Is Cold Enough That This Gas Would Condense Forming<br />
Ethane Lakes on the Surface of Titan<br />
• Titan is 94 o K (-179 o C)<br />
• It Is So Cold That H 2 0 Vapor Would Be Completely Lacking<br />
• Therefore: Lacking Any Appreciable Amount of Oxygen – Methane<br />
Remains Un-Oxidized, Adding to the Condensed Hydrocarbon Lake<br />
on the Surface of Titan
