2021-01-02 Between the years of 1785 and 1800, James Hutton and William Smith advanced the concept of geologic time and strengthened the belief in an ancient world. Hutton, a Scottish geologist, first proposed formally the fundamental principle used to classify rocks according to their relative ages.

During the geological time scale, different living organisms has undergone changes to a great level, among which some have got extinct and some comprised of such names which are not known to us even today. The time intervals and duration of each geologic time scale has a vast difference than today. It did not comprised of day, hours and minutes. The geologic time scale rather consists of eon The geologic time scale was developed by many different geologists between about 1800 and 1850.

It subdivides all time into named units of abstract time called—in descending order of duration— eons, eras, periods, epochs, and ages. The enumeration of those geologic time units is based on stratigraphy, which is the correlation and geological time-scale divides the history of Earth is divided into eons, e , periods and epochs.

This was done by making a linear time line on the left side of the time columns. Thicker units such as the Proterozoic were longer in duration than thinner units such as the Cenozoic.
