If you look at the four outer planets, they are composed largely of easily vaporized substances substances: hydrogen, helium, water, ammonia, and methane. These light, volatile substances, which accounted for most of the mass of the proto solar system, were driven out of the inner solar system by the strong solar wind of the young sun, leaving the inner planets with material that was mostly rock and metal.
