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 Triassic /traÉªËaesÉªk/ traÉªËÃ¦sÉªk is a geologic period and system that extends from roughly 250 to 200 (mya.252 Â± 17.0 06 to.201 Â± 3.0 2 million years), ago an interval of.51 04 million. Years it is the first period of The Mesozoic, era and lies between The permian And jurassic. periodso coal deposits date from the start of the Triassic period. This is known as the coal gap and can be seen as part of the PermianâTriassic extinction event. Sharp drops in sea level at the time of the Permo Triassic boundary may be the proper explanation for the coal gap.
