What is the study of the Earth's age?

Answer 1

There are several scientific fields that participate in the study of Earth's age.

Geologists study the age and make up of Earth and the chemistry and physics of the processes involved.

Geophysicist study particularly the physical processes of the Earth and to some degree other planets, with Earth's interior and earthquakes and geomagnetism being of particular note. The age of the Earth is an essential aspect of this.

Geochronology is the science of determining the age of earth's various structures, particularly rocks, fossils, and sediments.

Answer 2

The study of the Earth's age is known as geochronology. Geochronologists use various methods, such as radiometric dating of rocks and minerals, to determine the age of the Earth and the events that have occurred throughout its history. This field of study helps us understand the Earth's past and how it has evolved over billions of years.
