"It is used primarily by Earth scientists (including geologists, paleontologists, geophysicists, geochemists, and paleoclimatologists) to describe the timing and relationships of events in geologic history."
The study of Earth's history, including the evolution of life and major geological events.
Fossils: Preserved remains or traces of living organisms found in sedimentary rock layers that provide evidence of past life forms and the evolution of life on Earth.
Radiometric Dating: The process of determining the age of rocks and minerals based on the decay of radioactive isotopes, which can provide estimates of the age of the Earth and the timing of major events in geological history.
Stratigraphy: The study of rock layers and their relationships to one another in order to understand the geological history of an area or region.
Plate Tectonics: The theory that the Earth's crust is made up of a series of large plates that move and interact with one another over time, leading to the formation of mountains, earthquakes, and other geological features.
Geological Time Scale: A system of chronological dating that relates geological strata to time, providing a framework for understanding the relative timing of different geological events and the evolution of life on Earth over time.
Mass Extinctions: Periods in geological history when significant numbers of species went extinct, often due to major environmental changes or catastrophic events such as asteroid impacts or volcanic eruptions.
Geologic Formations: Distinctive layers of rock or sediment that have been deposited and transformed over time, often containing important information about the geological history of an area or region.
Earth's History: The study of the major events and changes that have occurred over time in the Earth's geology, climate, and biosphere, including the origin of life and the evolution of complex organisms.
"...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 time scale has been developed through the study of rock layers and the observation of their relationships and identifying features such as lithologies, paleomagnetic properties, and fossils."
"The definition of standardized international units of geologic time is the responsibility of the International Commission on Stratigraphy (ICS), a constituent body of the International Union of Geological Sciences (IUGS)."
"Their primary objective is to precisely define global chronostratigraphic units of the International Chronostratigraphic Chart (ICC) that are used to define divisions of geologic time."
"While some regional terms are still in use, the table of geologic time presented in this article conforms to the nomenclature, ages, and color codes set forth by the ICS."
"The chronostratigraphic divisions are in turn used to define geochronologic units."
"It is a system of chronological dating that uses the rock record of Earth."
