-
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.
Noachian
The Noachian is the oldest major geological era on Mars, characterized by heavy cratering, widespread valley networks, and conditions that may have supported liquid water on the surface.
-
C.
Lomagundi event
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.
Ludlow Epoch
The Ludlow Epoch is a division of the Silurian Period in the geologic timescale, marked by significant marine life diversification and characteristic sedimentary rock formations.
-
E.
Great Oxidation Event
The Great Oxidation Event was a pivotal period in Earth’s early history when atmospheric oxygen levels rose dramatically due to photosynthetic microorganisms, fundamentally transforming the planet’s environment and biosphere.
