Document Summary

Division of the world"s history ( 4 major subdivisions of geological time) Formation of the solar system and planet ends with origin of life first forms of life the earliest time in earth"s history. Partially molten surface collision with protoplanet to form moon; planet starts to cool down. 3,800 to 2,500 ma: anaerobic bacterial life, oxygen starts to accumulate, bacteria has to make atp from protons, protons strip off minerals. O2 started to accumulate by splitting h2o; iron oxide began to precipitate in oceans. O2 dissolves and forms oxides minerals: sulfur. Equilibrium between o2 and h2o starts to move into air. Origin and radiation of eukaryotes and simple multicellular organisms first transfer and copy of rna individual cells formed a colony and the resulting cells stick together (algae) Diversification of invertebrates, colonization of land by animals and plants rapid increase in diversity of plants/animals rocks and contain evident and abundant fossils. 543 to 251 ma, 63th to 65th.
