Why Do the Jovian Planet Interiors Differ

question 79

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 more distant planets had longer to form than the closer planets, since the solar nebula lasted longer at greater distances from the Sun.
