Testing the Steam Refund system. Last week, Steam finally did something many people have been waiting for, for quite some time: it instituted a refund policy. If you ask for a refund within 14 days of purchasing the game, and youâve played the game for less than two hours, congratulations! You can get your money back.
The units that divide the geologic time scale are Eons, Eras, Periods, and Epochs. Eons are the biggest, Eras are the second biggest and so on and so forth. So it goes Eons, Eâ¦ras, Periods, and then Epochs. I know this because i just took a test on it in science so i know its right.
http://geology.com/time/geologic-time-sc... It divides the earths geologic history into periods, eons and epochs to help us date when events happened. For example, dinosaurs died out at the KT boundary, ont he geologic time scale that is roughly 65 million years ago between the Cretaceous Period and Tertiary Period.
