Ocean basin rocks are basaltic (more dense) than continetial granitic rocks. 31. Solar eclipse must be at a New Moon at noon. 32. Ceres is the largest asteroid of 1000 km in diameter. In asteroid belt between Mars and Jupiter. 33. Chicxulub impact event is the most famous asteroid collision. Asterioid of 10km in diameter impacts earth in northern Mexico 65 million years ago. Extincts large dinosaurs 34. Chondrules froze so quickly they could not crystallize, glass like beads in chondritic meteorites. 35. Cold accretion is accretion very slowly (but heat was neated to differentiate). Aluminum to Magneisum accretion. Short-half life goes from cold to hot quickly.
