Document Summary

Geological time scale and life forms as well as building height (1floor 60ma, 72 floors, 12 feet/floor) Phanerozoic (543 ma to present time) (65 ma to present time, 72nd floor) Marine invertebrates, algae, (cid:363)cambrian explosion(cid:364), first land plants and insects. Anaerobic bacterial life, oxygen starts to accumulate. Formation of the solar system and planet, ends with origin of life. Solar systems heavy objects that are heavy enough to have gravitational pull. Pluto yes i know it"s not technically a planet but screw you. If you"re too close to the sun, you"ll be too small so you won"t have the gravity needed and no water because it"s too hot. If you"re too far away then water is frozen. (cid:363)carbon is central to life carbon atoms link in chains, bind with other atoms to make the array of organic chemicals that constitute life itself, from dna to toenails(cid:364) richard fortey life.
