Document Summary

Contains small rocky bodies, left over from formation of solar system, the rocks are far apart. Kuiper belt: outside of solar system, contains small bodies of dusty ice. Comet: small icy body, passes near sun to sublimate generating a coma (halo of ice and snow) or a tail. Frost lines marks the point where volatiles condense to ice particles, there particles formed the jovian planets. Jovian planets are not only ice and gas (jupiter has 30x mass of fe and. Escape velocity: velocity in which a particle can escape the gravitational pull of planet, increases with size of planet. Moon and mercury are likely too small to have co2, their escape velocity is too low. Earth used to be molten and mixed, then elements segregated. Atmophile elements: reside in ocean and atmosphere. Lithophile elements: reside in mantle and crust. Siderophile elements (iron loving): reside in core. Chalcophile elements (sulfur loving): reside in core. Magmaphile elements (magma loving): reside in crust.
