<P> The geologic time scale ( GTS ) is a system of chronological dating that relates geological strata ( stratigraphy ) to time . It is used by geologists , paleontologists , and other Earth scientists to describe the timing and relationships of events that have occurred during Earth 's history . The table of geologic time spans , presented here , agree with the nomenclature , dates and standard color codes set forth by the International Commission on Stratigraphy ( ICS ) . </P>
