The facts on the card
The card carries these facts from its Wikipedia article.
- On the geologic time scale, this comprises all of the Hadean eon and approximately one-third of the Archean eon, starting with the formation of the Earth about 4.6 Gya, and ended at the start of the Paleoarchean era 3.6 Gya.
- This period of Earth's history involved the planet's formation from the solar nebula via a process known as accretion, and transition of the Earth's atmosphere from a hydrogen/helium-predominant primary atmosphere collected from the protoplanetary disk to a reductant secondary atmosphere rich in nitrogen, methane and CO2.
- This time period included intense impact events as the young Proto-Earth, a protoplanet of about 0.63 Earth masses, began clearing the neighborhood, including the early Moon-forming collision with Theia , a Mars-sized co-orbital planet likely perturbed from the L4 Lagrange point , around 0.032 Ga after formation of the Solar System, which resulted in a series of magma oceans and episodes of…
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Early Earth article was read about 60,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 63 and blocks with 44: each hit it takes is cut by 18 %.
