Multiple Choice
According to modern theories, one significant difference between the formation of the terrestrial and jovian planets is that:
A) both formed by accretion of planetesimals, but the jovian planets became massive enough to attract gas onto them directly from the solar nebula.
B) both formed by accretion of rocky and icy planetesimals, but the terrestrial planets were close enough to the Sun that almost all of the ice escaped back to space after the planets formed.
C) the terrestrial planets formed close to the Sun where there was lots of rock but no ice, whereas the jovian planets formed far from the Sun, where there was lots of hydrogen and ice but no rocky material.
D) the terrestrial planets formed by accretion of planetesimals, whereas the jovian planets formed from streamers of hot gas that shot out of the protostar.
