Answer 1

Early in the solar system heat from the sun, combined with a strong solar wind from the sun’s formation drove most of the easily-vaporized material out of the inner solar system, leaving behind mostly rock and metal. Beyond a point called the frost line, between Mars and Jupiter, these materials remained in place so we got gas giants.
