Answer:
study information related to the Cenozoic era
Explanation:
A good understanding of the geologic time scale is required here.
The absolute age of 34mya for the Eocene falls in the Cenozoic era.
The geologic time scale is divide into Eons, Eras, Periods, Epoch, Age.
The Eons are larger divisions than any other group.
The GTS is divided into 4 era:
Precambrian
Paleozoic
Mesozoic
Cenozoic
The Precambrian era is the oldest while the Cenozoic is just a few million years.
The age of the Cenozoic lies between Recent to 66mya ago. This is where the Eocene should lie.
These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air). Each of these four spheres can be further divided into sub-spheres
The second one is most likely to be right
The Rocky Mountains. They are also the second longest mountain range in the world.
