Explain the purpose of a geologic time scale

Geologic time scales are essential tools for geologists and biologists alike because they help show the history of the entire world in terms of relationships between different plate movements.

Geologic time scales are essential tools for geologists and biologists alike as a result of they assist show the history of the whole world in terms of relationships between totally different plate movements.

Explanation:

Time could be an important variable in earth science, as a result of the exact timing of spatially separated events permits the United States of America to reconstruct the surface and surface conditions of the ancient earth. ... geological time spans area unit significantly more difficult to grasp than historical time spans as a result of they're therefore incredibly long.

In the geological timescale, time is usually divided on the premise of the earth's biotic composition, with the Phanerozoic aeon(i.e. the era, Mesozoic era and cenozoic Eras) representing the amount of Earth's history with advanced life forms, and therefore the Pre Cambrian (or Proterozoic and Hadean Eras.
