    EVENT 19 The last glacial period ended and sea levels rose, Great lakes formed. EVENT 28 Modern humans developed agriculture and used tools made of bronze and iron.

  • Anthropocene

    Anthropocene
    EVENT 7 Some scientist believe that humans kind has caused mass extinction of the plants and animals species, polluted the oceans and altered the atmosphere. EVENT 14 There is argument as to when this epoch began, some scientist think that it begn with the industrial age in the early 1800's other think it began with the atomic age in the 1950's.

  • Precambrian eon

    Precambrian eon
    EVENT 10 The presence of stromatolites indicate that shallow seas covered much of Earth during intervals in this period. EVENT 11 Nearly half of the valuable mineral deposits in the world occur in the rocks of this period.
