Answer:

The geologic time scale was developed after scientists observed changes in the fossils going from oldest to youngest sedimentary rocks. They used relative dating to divide Earth's past in several chunks of time when similar organisms were on Earth.

Answer:

Absolute time - numerical ages, often expressed in "millions of years before present". These are most commonly obtained by radiometric dating methods performed on appropriate rock types. ... Absolute time is the measurement taken from the same rocks to determine the amount of time that has expired.
