Answer 1

Answer:

You can view the ICS time scale online. It would be a good idea to print a copy (in colour) to put on your wall while you are studying geology. Geological time has been divided into four eons: Hadean (4570 to 4850 Ma), Archean (3850 to 2500 Ma), Proterozoic (2500 to 540 Ma), and Phanerozoic (540 Ma to present).
