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.
Geologic time. The geological time scale (GTS) is a system of chronological measurement that relates stratigraphy to time, and is used by geologists, paleontologists, and other Earth scientists to describe the timing and relationships between events that have occurred throughout Earth's history.
