Ammonia (NH3), Ammonium Hydrosulfide ((NH3)SH), and water (H20)
The major difference between Saturn and Jupiter's Belt-zone circulation is what?
It is not as distinct
Why are Saturn's zones and belt not as distinct?
Because they occur deeper inside of Saturn's colder atmosphere below a layer of methane haze
