Life has been present on Earth for approximately 85-90% of its 4.6 billion-year history, with evidence of microbial life dating back around 3.5 billion years. This indicates that microbial life existed on Earth for most of its existence.


Geologists have divided earths history in the manaeable units that are represented by the?

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.


What is the usefulness of categorizing earths history into the geologic time scale?

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.


Why is geologic time scale used to show earths history?
