-
A.
Paleoproterozoic Era
chosen
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.
-
B.
Mesoproterozoic Era
The Mesoproterozoic Era was a middle division of Earth's Proterozoic Eon characterized by the stabilization of continental cratons, widespread sedimentary basin development, and significant evolutionary advances in eukaryotic life.
-
C.
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.
-
D.
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.
-
E.
Paleoarchean Era
The Paleoarchean Era is an early division of Earth's geologic history marked by the stabilization of the first continental crust and the emergence of some of the oldest known life forms.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
