-
A.
Late Heavy Bombardment era
chosen
The Late Heavy Bombardment era was a hypothesized period about 4.1–3.8 billion years ago during which the inner Solar System, including bodies like the Moon and Mercury, experienced an intense spike in asteroid and comet impacts that heavily cratered their surfaces.
-
B.

The Lomagundi event was a prolonged Paleoproterozoic episode of unusually high carbon isotope ratios in marine carbonates, interpreted as evidence for a major global increase in oxygen production and organic carbon burial.
-
D.
Rhyacian Period
The Rhyacian Period is a geologic time interval in the early Proterozoic characterized by significant crustal growth, widespread metamorphism, and some of the earliest known large-scale glaciations.
-
E.
Marinoan glaciation
The Marinoan glaciation was a major Neoproterozoic ice age, likely a global or near-global “Snowball Earth” event that occurred around 650–635 million years ago.
