Question 11. use the definitions of refractory and volatile to explain where you expect rocky planets/moons vs icy planets/moons to develop in the solar system relative to distance from the host star and why. include the snow-line/ice-line 15 pts

As explained below.

Explanation:

From the use of the definition of Refractory and Volatility which means the resistance to decomposition and evaporation of matter the rocky planets or the moon as compared to the icy planets like Saturn in the solar system is quite complex. As the host star i.e the sun is a yellow giant made of gases of hydrogen and helium has the capacity to drive away the atmosphere of the planets that nearby with the help of solar winds and the four terrestrial planets are rocky and the other end three planet are gas giants. The planet like Saturn, Uranus and Neptune are quite far and have high densities of gases and ice, even frozen water running underground there surfaces. As the planet becomes voitialie it loses its refractory as has happened with venus and mars. Thus even moon shows some layers of ice found in its creators.

Ithink the answer is b
