“ARCHEAN”
(“eon #2”)
(1.5 billion years)
The Archean Eon (pronunciation: /ɑːrˈkiːən/, also spelled Archaean) is a geologic eon, 4,000 to 2,500 million years ago (4 to 2.5 billion years), that followed the Hadean Eon and preceded the Proterozoic Eon.
(during the Archean, the Earth’s crust had cooled enough to allow the formation of continents)
