    Atmospheres on Other Planets

    The processes affecting Earth's atmosphere can also be seen on other planets. For instance, Jupiter, a planet about 318 times more massive than Earth has similar atmospheric circulation zones and bands (Figure 8.47). On Jupiter, the bright zones are regions of rising cloud tops, and the dark zones are regions of sinking air. Bright spots on Jupiter are massive cyclones (some are larger than planet Earth!). Jupiter's upper atmosphere is composed of hydrogen, helium, and has clouds composed of ammonia ice crystals (NH3).
