Unformatted text preview: Saturn has the same three main cloud decks, though they are found at lower altitudes than on Jupiter because of Saturn's lower temperature (it is further from the Sun). Also, Saturn's cloud decks are further apart from each other because of Saturn's lower gravity---there is less compression of the gases. Because Saturn's clouds form at deeper positions in its troposphere, its cloud patterns appear more muted than on Jupiter. It is thought that the three cloud decks (of ammonia, ammonium hydrosulfide, and water) would be found much too deep in the tropospheres of Uranus and Neptune for us to see. Instead, Uranus and Neptune being even further from the Sun have cold enough tropospheres for methane to condense and freeze to form clouds (Jupiter and Saturn are too warm for methane clouds). Neptune has extra heat energy from its interior so its atmosphere temperature is warmer than Uranus....
