Which of the following statements best describes the general pattern of composition among the four jovian planets? a) jupiter is made mostly of hydrogen, saturn is made mostly of helium, uranus is made mostly of hydrogen compounds, and neptune is made mostly of rock. b) jupiter is made mostly of hydrogen and helium, while the other three jovian planets are made mostly of hydrogen compounds. c) all four planets have essentially the same composition. d) jupiter and saturn have compositions that are fairly different from the compositions of uranus and neptune.

Jovian Planets (means "similar to Jupiter") is the name given to the "gaseous giant" planets of our solar system. Although they share many similarities, they have certain differences.

For example, Jupiter and Saturn are classified as "gas giants", while Uranus and Neptune are "ice giants".

This is also due to the fact that Uranus and Neptune have higher concentrations of methane (hence its bluish color) and some heavier elements such as oxygen, carbon, nitrogen, and sulfur. On the other hand, Jupiter and Saturn tend to be orange-white in appearance due to the mixture of hydrogen that gives off a red aspect.
