how does the solar nebula theory explain the significant density difference between the terrestrial and jovian planets? (select all that apply.) the increased angular momentum of the outer planets caused them to contract into more dense objects. the gravity of the sun pulled all gases away from the inner planets, but did not reach the outer planets, leaving them with less dense material. jovian planets started out with solid material as well, and were far enough from the sun for a layer of ice to form, after which they became massive enough to capture slower-moving gases. the large gravitational pull of the forming outer planets caused them to be bombarded by high-density comets, asteroids, and planetesimals. terrestrial planets formed from solid material that condensed out of the solar nebula close to the sun, where it was too hot for them to capture gases.
