Remember, the drug label will tell you: 1  what the drug is used for. 2  how to take the drug. 3  how to reduce the risk of drug interactions and unwanted side effects.
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, E â¦ ras, Periods, and then Epochs. I know this because i just took a test on it in science so i know its right.
The correct arrangement of the different types of geologic time divisions, from longest to shortest, is: A. epochs, periods, eras, eons B. periods, eons, epochs, eras C. eons, eras, periods, epochs D. eons, epochs, eras, periods E. eras, periods, epochs, eons 18.he time divisions in the Geologic Column that represent the longest lengths of time are called: A. eras B. epochs C. eons D. periods E. years 18. The Hadean, Archean, and Proterozoic eons are collectively called the: A. Phanerozoic B. Mesozoic C. Holocene D. Precambrian E. days of yore 18.
