Why do the jovian planet interiors differ?
 
  A) 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.
  B) They differ due to giant impacts at the late stages of planet formation.
  C) The more distant planets had longer to form than the closer planets, since the solar nebula lasted longer at greater distances from the Sun.
  D) 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.

Answer to Question 1

A

Answer to Question 2

A white dwarf in a close binary system accretes mass from its companion star. This mass is mostly hydrogen from the companion's outer layers. When enough builds up on the white-dwarf surface, the hydrogen undergoes fusion, generating the nova.
