1. The correct answer is B. The nebular theory states that the solar system is the result of the collapse, for unknown reasons, of a large, thin cloud of dust and gas. After this collapse<span>, the pockets of gas and dust started gathering into denser regions. As these regions collected more and more matter, they started to rotate, which led to the accumulation of a big ball in the </span>center<span>, the Sun, and </span>flattenedmatter around, the protoplanetary disc. Then the planets got formed by the accretion of this disc, which eventually created the planets.
2. The correct answer is D. The terrestrial<span> planets were formed by </span>accretion<span> of material that was denser in its constitution. This is the reason why they remained closer to the sun - they were heavier than gas, that is the material the Jovian planets are mostly made of.</span><span />
