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.
Absolute geologic time places ages on geologic events or units. Relative time gives qualitative comparisons between events. Example of absolute geologic time: Rock A is 400 million years old. Example of relative geologic time: Rock B is younger than Rock A, but older than Rock C. It would be like saying: I am 35 years old (absolute time), and am older than my brother (relative geologic time).
