Why Do the Jovian Planet Interiors Differ

Multiple Choice

Why do the jovian planet interiors differ?

A) The more distant planets formed in a cooler region of the solar nebula and therefore contain a greater proportion of ices than the closer jovian planets.
B) They differ due to giant impacts at the late stages of planet formation.
C) Accretion took longer further from the Sun,so the more distant planets formed their cores later and captured less gas from the solar nebula than the closer jovian planets.
D) The solar heating is less for the more distant planets than the closer planets.
E) The more distant planets had longer to form than the closer planets,since the solar nebula lasted longer at greater distances from the Sun.
