1. binary or close encounter hypothesis of Solar System origin -- probability and its implications; basic problem, confrontation with observation 2. nebular theory of Solar System origin -- gravitational contraction of nebula, angular momentum conservation and spin, protosun and protoplanetary disk; angular momentum problem and solution; condensation sequence (volatiles, refractories and examples) and temperature gradient, "frost line;" accretion and planetesimals, nebular capture, solar wind; asteroids and comets as "leftovers" 3. cratering history of Moon, early vs. late bombardment, impact basins and lunar maria; giant impact theory of Moon's origin; cratering history of Mercury 4. other planetary systems -- direct detection and difficulties; indirect detection using astrometry ("wobble"), orbital Doppler effect, transits, microlensing 5. interior structure of terrestrial planets -- core, mantle, crust and lithosphere; differentiation; heat sources (accretion, radioactivity, differentiation itself) and transport (conduction, convection and circulation) 6. Earth's magnetic field -- dynamo mechanism and requirements (electrically conducting liquid, rotation, convection); geometry and solar wind; other terrestrials 7. geological activity of terrestrials -- plate tectonics, continental drift (Earth only); mantle convection and uplift, other tectonic processes; shield volcanoes on Earth, Mars, and Venus; bulges on Venus and Mars (e.g. Tharsis); relative activity levels on terrrestrial planets and Moon 8. atmospheres of terrestrial planets -- original and solar wind stripping; outgassing;
