    Option 1: Use the pie chart below to plot the eons of geologic time: Hadean, Archean, Proterozoic, and Phanerozoic. Calculate the percentage of time each eon makes up and plot them on the pie chart below. For example, the Hadean represents 600 myrs of geologic time, or about 13% ( (600 myr/4600 myr) * 100).

    The primary objective of the International Commission on Stratigraphy (ICS) is to precisely define global units (systems, series, and stages) of the International Chronostratigraphic Chart that, in turn, are the basis for the units (periods, epochs, and age) of the International Geologic Time Scale.

    “The age of 4.54 billion years found for the Solar System and Earth is consistent with current calculations of 11 to 13 billion years for the age of the Milky Way Galaxy (based on the stage of evolution of globular cluster stars) and the age of 10 to 15 billion years for the age of the Universe (based on the recession of distant galaxies).”
