    The Archean Eon marked a time when Earth's climate began to stabilize.

    Earth cooled down from its molten state. It eventually could support oceans. Tectonic activity built continents.

    In the Archean Eon, oxygen filled the atmosphere and most of the world's iron ore was deposited.

    Because the Earth's conditions stabilized, eukaryotic and multicellular life could finally emerge in the Proterozoic Eon.
