-
A.
Precambrian Supereon
chosen
The Precambrian Supereon is the vast span of Earth's early history before the Phanerozoic, encompassing the Hadean, Archean, and Proterozoic eons during which the planet formed, life first appeared, and early continents and atmospheres developed.
-
B.
Archean Eon
The Archean Eon is an ancient geological eon of Earth's history, spanning from about 4.0 to 2.5 billion years ago, characterized by the formation of the first stable continental crust and the earliest known life.
-
C.
Proterozoic Eon
The Proterozoic Eon is a major division of Precambrian time, spanning from about 2.5 billion to 541 million years ago, marked by the buildup of atmospheric oxygen, the emergence of complex single-celled and early multicellular life, and the assembly of large continental landmasses.
-
D.
Hadean Eon
The Hadean Eon is the earliest interval of Earth's history, marked by planetary formation, intense bombardment, and a largely molten surface before the emergence of stable crust and oceans.
-
E.
Neoproterozoic Era
The Neoproterozoic Era was the final era of the Proterozoic Eon, marked by global “Snowball Earth” glaciations and the emergence of early multicellular life leading up to the Cambrian explosion.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
