Question
Which statement is true with regard to the characteristic composition of the Jovian (Gas Giant) planets in the Solar System?
Answer
Although it is expected that these planets have iron-nickel and silicate cores they are primarily composed of hydrogen and helium.
These planets demonstrate a wide variation of compositions. Some are primarily an iron-nickel compound, others are composed of silicates, others are primarily composed of silicates and organic compounds, others are rich in water ice and other volatile compounds, while others have compositions that are a variety of combinations of all these.
Although these planets have iron-nickel cores, they are primarily composed of silicates.
These planets may contain silicates, but have a high concentration of volatile ices that can be observed on their surfaces.
