What defines a geological period?
From Wikipedia, the free encyclopedia. A geological period is one of the several subdivisions of geologic time enabling cross-referencing of rocks and geologic events from place to place. These periods form elements of a hierarchy of divisions into which geologists have split the Earth’s history.
What are the 5 eras of geologic time?
This scale is most detailed for the time in which life was abundant, as shown by fossils.Geological Timescale. The oldest fossils are between 3 billion and 3.5 billion years old. … Phanerozoic Eon. … Paleozoic Era. … Mesozoic and Cenozoic Eras.
What are eons eras and periods?
To make geologic time easier to comprehend, geologists divided the 4.6 billion years of Earth’s history into units of time called eons. Then they further divided the eons into two or more eras, eras into two or more periods, periods into two or more epochs, and epochs into two or more ages.
How long is an eon?

What time period is 2020?
Currently, we’re in the Phanerozoic eon, Cenozoic era, Quaternary period, Holocene epoch and (as mentioned) the Meghalayan age.
What era do we live in 2020?
According to the International Union of Geological Sciences (IUGS), the professional organization in charge of defining Earth’s time scale, we are officially in the Holocene (“entirely recent”) epoch, which began 11,700 years ago after the last major ice age.
How are geologic periods named?
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.
How long is a period?
