The dependence of planetesimal composition on distance from the Sun and the existence of the frost line resulted in two main types of planet
The dependence of planetesimal composition on distance from the Sun and the existence of the frost line resulted in two main types of planets in our Solar System: the inner rocky planets and the outer gas giants. The gas giants are observed to be made mostly of hydrogen and helium. Given this observation and what you have learned about planetesimal formation through accretion, and the types of materials that condensed at that distance from the Sun, which of the following is the most likely way that the gas giants formed?
A. They must have formed elsewhere and been captured by the Sun’s gravity because hydrogen and helium could not condense into a solid at the temperature of the Solar Nebula.
B. Hydrogen and helium condensed into a solid and accreted to form the gas giants.
C. Rock, metal, and ices made of materials like water, ammonia, and methane condensed into a solid and grew large enough to gravitationally attract hydrogen and helium gas from the Solar Nebula.
