Which gases are found in the atmosphere on the gas giants?

Gas giants, such as Jupiter and Saturn, primarily consist of hydrogen and helium, which make up the majority of their atmospheres. In addition to these dominant gases, trace amounts of methane, ammonia, water vapor, and other hydrocarbons can also be found. Uranus and Neptune, the ice giants, contain higher concentrations of water, ammonia, and methane, contributing to their distinctive blue color. Overall, the atmospheres of gas giants are characterized by their complex mixtures and dynamic weather systems.
