Chronostratigraphic Units

Chronostratigraphic units are categories used by geologists to describe and classify layers of rocks based on their age and the time period they represent. These units help scientists understand the history of the Earth by organizing rock layers into specific timeframes, such as the Paleozoic or Mesozoic eras. Each unit corresponds to significant events in geological time, such as the formation of mountains or the extinction of species, allowing researchers to track changes in the Earth's environment and life forms over millions of years.
