Question

Study the geologic time scale.

A geologice time scale. 4,600 M Y A to 544 M Y A, Precambrian Time. 544 M Y A to 250 M Y A, Paleozoic Era. 250 M Y A to 65 M Y A, Mesozoic Era. 65 M Y A to Today, Cenozoic Era.

The Eocene period exists in Earth’s history around 34 MYA.

What could a scientist do to determine what era the Eocene period belongs to on the geologic time scale?

learn what happened during Precambrian time
study information related to the Cenozoic era
view the timing of events in the Mesozoic era
research events that happened during the Paleozoic era

Answer 1

Study information related to the Cenozoic era.

Reason: the Cenozoic spans 65 M Y A to today, and the Eocene (~34 M Y A) falls within that range, so comparing the Eocene's age to the era time ranges shows it is part of the Cenozoic.
