(a) Both were the same initially, accretion through collisions of larger and larger planetesimals, but the inner planets stopped there whereas the outer planets went on to pull ices and gas directly from the solar nebula. (b) Both were very different from the start, the inner planets forming by accretion through collisions of larger and larger planetesimals, and the outer planets by condensation of ices and gas directly from the solar nebula. (c) Both formed by the same process, accretion through collisions of larger and larger planetesimals, but the planetesimals forming the inner planets were rocky whereas those forming the outer planets were composed mostly of ices.
