Geologic Time Scale Chronology is the science of organizing events in the order they happened in time. Introducing Timelines What are some events that all of us have had in our lives? Ask the class ...

Geologic Time is a crucial concept to understanding the history of the earth—including the evolution of life. Many different representations of the timeline have been created, and many approaches ...

The Anthropocene (The Age of Humans) has been proposed as a new geological epoch after or within the Holocene, and, if formalized, would be the first to be introduced based on geologically observable ...

New Astronomical Results Refine The Geological Time Scale Date: November 3, 2004 Source: Journal Astronomy & Astrophysics Summary: A team led by Jacques Laskar from the Institut de Mécanique ...

This is standard procedure when defining units of the International Geological Time Scale”. Event stratigraphy is the study of the traces of (geologically) short-lived events – lasting up to thousands ...

Dividing up deep time The geologic time scale provides the official framework for our understanding of Earth’s 4.5 billion-year history.

Geologists may have voted down formal recognition of the Anthropocene as a geological epoch, but we still need to act to prevent ecological crisis.

Many of the slices of the Geologic Time Scale are divided by when big events cause big changes and there are a significant number of Earth scientists that say that the rise of human civilization is ...

The geologic time scale divides Earth’s 4.6 billion-year story into grandly named chapters. Like nesting dolls, the chapters contain sub-chapters, which themselves contain sub-sub-chapters.

The proposal to add an Anthropocene Epoch to the geological time scale was rejected for a variety of reasons, none of them related to the fact that human societies are changing this planet.

Scientists have identified the geological site that they say best reflects a proposed new epoch called the Anthropocene — a major step toward changing the official timeline of Earth’s history.
