What is the order of the geologic timescale?
The geologic time scale is the “calendar” for events in Earth history. It subdivides all time into named units of abstract time called—in descending order of duration—eons, eras, periods, epochs, and ages.

What geological period are we currently in?
The Anthropocene Epoch is an unofficial unit of geologic time, used to describe the most recent period in Earth’s history when human activity started to have a significant impact on the planet’s climate and ecosystems.
What era are we currently in *?
Cenozoic era
Currently, we’re in the Phanerozoic eon, Cenozoic era, Quaternary period, Holocene epoch and (as mentioned) the Meghalayan age.
What are the 12 geologic time periods?
What are the 12 geologic time periods? The names of the eras in the Phanerozoic eon (the eon of visible life) are the Cenozoic (“recent life”), Mesozoic (“middle life”) and Paleozoic (“ancient life”). The further subdivision of the eras into 12 “periods” is based on identifiable but less profound changes in life-forms. Click to see full answer.
What is the current geologic time period?
Officially, the current epoch is called the Holocene, which began 11,700 years ago after the last major ice age. However, the Anthropocene Epoch is an unofficial unit of geologic time, used to describe the most recent period in Earth’s history when human activity started to have a significant impact on the planet’s climate and ecosystems.
What is the Order of the geologic time scale?
This is most easily done by first breaking the time scale into its component parts: eons, eras, periods, and epochs. The eon is the broadest category of geological time. Earth’s history is characterized by four eons; in order from oldest to youngest, these are the Hadeon, Archean, Proterozoic, and Phanerozoic.
