_______ would be most likely observed at a transition between divisions of an eon.

Question

Quizplus · Accepted Answer

Large changes in assemblages of fossil organisms contained in successive strata would be the most likely observation at a transition between divisions of an eon. This is because the assemblages of fossils found in different layers of rock can provide evidence of changes in biological diversity and environmental conditions over time. A transition between divisions of an eon would likely represent a significant period of geological time, with major changes in the kinds of organisms that lived and the conditions under which they lived. In contrast, large changes in the rate or absolute amounts of radioactive substances would not necessarily be tied to transitions between eon divisions, and violations of the principles of stratigraphy would be unlikely to occur. Little difference between the layers would also be unlikely to occur, as eon divisions are typically marked by significant changes in geological and biological history.
