SCCC 115 Homework 8 - Due 06 Nov. 2005 Prof. Christina Lacey R&D: 11-20, 12-16, 15-8, 15-10, 15-12 P: 12-3, 12-5, 13-3 Water is relatively uncommon among the terrestrial planets. Is it common among the moons of Jupiter. Yes, there is much water on many of the moons of Jupiter and even in Jupiter itself. The cooler temperatures in the outer part of the solar system aided the formation of the solid water and made it possible for the water to remain. Why does Titan have a dense atmosphere when other large moons in the solar system do not? The most important reason is Titan's greater distance from the Sun. Titan's temperature is 94 K, which comes from heating of Titan by solar radiation. At 94 K, the escape speed is low and methane and ammonia condense or freeze, which helped Titan retain these molecules as did absorption of methane and ammonia by water ice. As Titan's internal radioactivity warmed the moon, the ice released the trapped gases into the atmosphere. Sunlight split the ammonia into hydrogen and nitrogen. The hydrogen was able to escape, but nitrogen is heavier and
