The outer planets are sometime collectively called the gas giants. That name is perhaps a bit misleading given how we think of gas in earth-based situations. However the most abundant gas in the solar nebula – hydrogen – is certainly the primary ingredient of all four Jovian planets.
In a 2-3 paragraph essay outline some of the major differences among the Jovian planets. Describe the process of gas capture that helped to build them and use it as a basis to explain these differences.
