Geological time is divided into periods known as what?

Teachers become fallible when they stop learning information to share with students ...

Not all stretches of time are measured in epochs in geology. There are periods, eras, eons, ages. Each of these have identifying characteristics such as ice ages - which in turn have epochs. A better question would be more say: some of the stretches of time in geology are epoch.

My English teacher told me "epoch" wasn't a word. The dictionary proved otherwise.

Jecca, who is that

epoch is a period of time.

Jecca, I’m so happy that cartoons are working in our favor!

thank you Rick & Morty! lol
