Temperature variations within the protoplanetary disk were most responsible for the differentiation between the planets. Closer to the Sun, the higher temperatures allowed only metals and silicates to condense, forming the terrestrial planets, while farther away, cooler temperatures allowed ice and gas to condense, leading to the formation of gas giants and ice giants.
