Answer to Question 1

White ammonia ice makes up the zones of Jupiter and Saturn, and combines with hydrogen sulfide and other chemicals to make up the brownish belts. But it is not as common at Uranus and Neptune, perhaps instead dissolved in their water mantles. At Uranus and Neptune, methane is the chief coloring agent, absorbing red light strongly, and reflecting the blue light back into space.
