A.
Holocene Baltic Sea stages
Holocene Baltic Sea stages are the successive geological and hydrological phases of the Baltic Sea’s development during the Holocene epoch, characterized by changing sea levels, salinity, and connections to the world ocean.
-
B.
Eocene–Oligocene climate transition
The Eocene–Oligocene climate transition was a major global cooling event around 34 million years ago that marked the shift from a greenhouse to an icehouse Earth, including the formation of large Antarctic ice sheets.
-
C.
Milankovitch cycles
Milankovitch cycles are long-term variations in Earth’s orbit and axial tilt that drive natural climate fluctuations, including the timing of ice ages.
-
D.
Cenozoic glaciations
chosen
Cenozoic glaciations are a series of major ice age cycles during the Cenozoic Era that saw extensive growth and retreat of continental ice sheets, profoundly shaping Earth’s climate and landscapes.
-
E.
Paleogene climatic optimums
Paleogene climatic optimums were intervals of exceptionally warm global climate during the Paleogene Period that set the stage for the cooler conditions of the subsequent Neogene.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
