IMPLICATION OF PLANET FORMATION MODELS FOR THE INITIAL STATE OF EARTH
David Stevenson (CALTECH)

I will present a brief summary of current research and a set of discussion topics that focus on the physical consequences of planet formation for planetary structure. These necessarily depend on the dynamics of accumulation (but I am not expert on that). Here are some of the questions under consideration: What is the meaning of current isotopic indications of formation time scales (especially Hf-W)? What is the difference in outcome for accretion involving a lot of small bodies relative to accretion involving a small number of large bodies? What does the state of Earth's core and mantle tell us about accretion? What about atmosphere and hydrosphere? What does the Moon tell us ? What do the other terrestrial planets tell us?
