The Geologic Time Scale is illustrated here to help you see the way geologists have broken down geologic time into sections, each with an interesting and fascinating name, and each containing a package of rocks deposited during a certain time period…over the world.
That is because the PG knows that certain conditions existed on earth during each of the geologic time periods.
As soon as a living organism dies, it stops taking in new carbon.

The Grand Canyon is one of the most recognizable landforms on planet Earth and the most often asked question about it is, "When did it form? Geologists still debate many of the details about the origin and age of the canyon but recent geologic research has shed new light on the topic.
Using new, sophisticated laboratory techniques geologists are able to tease ever more information from the canyon's seemingly stubborn rocks.
