Document Summary
Geo - lec 5 - planets - differentiation of the earth - origin of the ocean, atmosphere, and the. Hosts a vast collection of small bodies of rocks (some ice) left over from formation of solar system. Did not form into a planet b/c they are too strongly perturbed by jupiter"s gravity. Pass close enough to the sun to sublimate, generating a coma (halo of ice and dust) Believed to originate in kuiper belt and beyond. Close to sun, too hot for volatiles to condense and form ice particles. Beyond frost line temperature low enough for volatiles to condense into ice particles, forming the jovian planets. More mass that won"t melt in outer part of solar system, more gravity, therefore larger planets with immense gaseous atmospheres. Jupiter: 30x the mass of earth present in silicate and iron (has a core made of rock, metals, and hydrogen) Frost line : separates jovian and terrestrial planets.
