Answer:
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.

Dew point is the temperature of an air mass in which the water vapor (humidity) starts to condense into droplets due to saturation. This is when dew begins to form.
Explanation:
The higher the temperature the higher the water vapor the air mass can hold. This is because the intermolecular spaces between the air molecules become larger with increased temperature hence can accommodate more water vapor molecules in between the air molecules. As the air mass cools the intermolecular spaces become shorter and the relative humidity of the air mass increases. At temperatures where the air mass can't accommodate its humidity, this is called the dew point, and the water vapor begins to condense into droplets (dew).
