The geologic time scale helps to organize Earth's history into manageable segments based on significant events and changes. It allows scientists to study and understand the timing of key geological and biological events, such as mass extinctions or the formation of mountain ranges. By providing a framework for organizing this vast expanse of time, the geologic time scale aids in our understanding of Earth's evolution and the processes that have shaped our planet over billions of years.
Geologists have divided Earth's history into manageable units called eons, eras, periods, and epochs. These divisions help scientists study and understand the Earth's geological and biological history over millions of years.
because the time span of earth past is so great geologic
The table you are referring to is likely the Geologic Time Scale. It divides Earth's history into different time periods based on significant events and changes in the planet's geology, climate, and life forms. These time periods are typically grouped into eons, eras, periods, epochs, and ages.
Nitrogen has made up the largest portion of Earth's atmosphere for most of Earth's history. It currently makes up about 78% of the atmosphere.
The measurement of Earth's history divided into time periods is called the geological time scale. It is divided into eons, eras, periods, epochs, and ages, with each unit representing a significant change in Earth's geological and biological history.

The division of geologic time that makes up about 88 percent of Earth's history is called the Precambrian eon. It spans from the formation of Earth around 4.6 billion years ago to the beginning of the Phanerozoic eon around 541 million years ago.
The Earth's history is divided into geologic time periods, with the largest unit being eons, which are further divided into eras, periods, epochs, and ages. The current eon we are in is the Phanerozoic eon, divided into the Paleozoic, Mesozoic, and Cenozoic eras. Each division represents significant changes in Earth's geological and biological history.
