Formation of the Earth and Solar System How do the inner planets (including earth) differ from outer planets in terms of size and  composition?    The solar system began as a nebula. Describe the nebula in terms of shape and composition.     How did the proto-sun (early version of the sun, not as bright or dense as today) form?     Why did the spin rate of the solar nebula increase? What important effect did this have on the  shape of the nebula?     Describe the temperature gradient in the accretion disk around the sun.     How did this gradient influence the distribution of planet types          (i.e., why are inner planets dominantly rocky material and the outer planets dominantly  frozen gases?)     After small solids began to condense in the disk around the sun, how did this material form  planets?     Which is more dense (average), the earth or the moon?  Where is most of the mass in the solar system found? What is the estimated age for formation of the solar system and where does this age come from?
