What is the geologic time scale what information does it provide?

Explanation: The geologic time scale (GTS) is a system of chronological dating that relates geological strata (stratigraphy) to time. It is used by geologists, paleontologists, and other Earth scientists to describe the timing and relationships of events that have occurred during Earth’s history.

Who discovered geological time scale?

The first geologic time scale that included absolute dates was published in 1913 by the British geologist Arthur Holmes. He greatly furthered the newly created discipline of geochronology and published the world-renowned book The Age of the Earth in which he estimated Earth’s age to be at least 1.6 billion years.

What is the purpose of a geological time scale?

The geologic time scale (GTS) is a system of chronological dating that classifies geological strata (stratigraphy) in time. It is used by geologists, paleontologists, and other Earth scientists to describe the timing and relationships of events in geologic history.

Why is it important to know the geologic time scale?

The geologic time scale is an important tool used to portray the history of the Earth -a standard timeline used to describe the age of rocks and fossils, and the events that formed them. It spans Earth’s entire history and is separated into four principle divisions.

What do scientists use to determine the geologic time scale?

Index fossils are used in the formal architecture of geologic time for defining the ages, epochs, periods, and eras of the geologic time scale. The evidence for these events is found in the fossil record wherever there is a disappearance of major groups of species within a geologically short amount of time.

What are the eras and periods of the geologic time scale?

Eons are the largest spans of time in the geologic time scale. Eons are divided into smaller units called eras. Eras are subdivided into periods. Periods are subdivided into even smaller time spans called epochs.

What information does the geologic time scale provide?

The information that geologic time scale provide is end date of a geological period and reasons why organisms evolve into different species.
