13 wrz 2024 · 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. The enumeration of those geologic time units is based on stratigraphy, which is the correlation and classification of rock strata.

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).
Today, the geologic time scale is divided into major chunks of time called eons. Eons may be further divided into smaller chunks called eras, and each era is divided into periods . Figure 12.1 shows you what the geologic time scale looks like.
Interactive Geological Timescale. This visualisation of the International Commission on Stratigraphy 's Chronostratigraphic Chart uses the SKOS & Time Ontology in OWL representation of it as the Geological Timescale (2020) for its data.
6 gru 2023 · 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.
Introduction. Encyclopædia Britannica, Inc. Source: International Commission on Stratigraphy (ICS) The vast interval of time that spans Earth’s geologic history is known as geologic time. It began roughly 4.6 billion years ago when Earth began to form as a planet and extends to the present day.
Describe the principles of relative dating. Summarize the process of absolute dating. Recognize the hierarchy of the geologic time scale and names of specific sections of geologic time. Introduction. The Earth is 4.566 billion years old. [1] Knowing this is not simply some esoteric piece of trivia.
