Geologic time scale - Wikipedia
7 Apr 2025 at 3:44pm
The geologic time scale or geological time scale (GTS) is a representation of time based on the rock record of Earth. It is a system of chronological dating that uses chronostratigraphy (the process of relating strata to time) and geochronology (a scientific branch of geology that aims to determine the age of rocks).

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.

Humans subdivide time into useable units such as our calendar year, months, weeks, and days; geologists also subdivide time. They have created a tool for measuring geologic time, breaking it into useable, understandable segments. For the purposes of geology, the ?calendar? is the geologic time scale.

Its primary objective is to precisely define global units (systems, series, and stages) of the International Chronostratigraphic Chart that, in turn, are the basis for the units (periods, epochs, and age) of the International Geologic Time Scale; thus setting global standards for the fundamental scale for expressing the history of the Earth.

The Geologic Time Scale is a system used by scientists to describe the timing and relationships between events in Earth's history. It covers a vast expanse of time, from the formation of the planet nearly 4.6 billion years ago to the present day.

A geologic time scale is composed of standard stratigraphic divisions based on rock sequences and is calibrated in years (Harland and others, 1982). Over the years, the development of new dating methods and the refinement of previous methods have stimulated revisions to geologic time scales.

The Geologic Time Scale or Geological Time Scale (GTS) is a chronological framework that organizes Earth?s history into various units based on geological and paleontological evidence. It divides Earth?s 4.6 billion-year history into hierarchical units such as eons, eras, periods, epochs, and ages.

The geologic time scale is a system used by scientists to describe Earth's history in terms of major geological or paleontological events (such as the formation of a new rock layer or the appearance or demise of certain lifeforms).

Scientists have put together the geologic time scale to describe the order and duration of major events on Earth for the last 4 1 ? 2 billion years.
