Target entity: Proterozoic Eon Context triple: [Rodinia, geologicalEon, Proterozoic Eon]
-
A.
Proterozoic Eon
chosen
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.
-
B.
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.
-
C.
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.
-
D.
Paleoproterozoic Era
The Paleoproterozoic Era was an early division of Earth's history marked by the stabilization of continental cratons, widespread banded iron formations, and the Great Oxidation Event that significantly increased atmospheric oxygen.
-
E.
Precambrian Supereon
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.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
