Geologic time scale relative dating

Video details
The geologic time scale GTS is a system of chronological dating that classifies geological strata stratigraphy in time. It is used by geologists , paleontologists , and other Earth scientists to describe the timing and relationships of events in geologic history. The time scale was developed through the study of physical rock layers and relationships as well as the times when different organisms appeared, evolved and became extinct through the study of fossilized remains and imprints. The table of geologic time spans, presented here, agrees with the nomenclature , dates and standard color codes set forth by the International Commission on Stratigraphy ICS. The primary and largest catalogued divisions of time are periods called eons. The first eon was the Hadean , starting with the formation of the Earth and lasting over million years until the Archean , which is when the Earth had cooled enough for continents and the earliest known life to emerge.

3. Geological time scale

Placing of events in the order in which they occurred without any relationship to the actual time during which any one event occurred is known as relative dating. It is a qualitative way of describing the sequence of events. The sequence orders the events but provides no information to the amount of time passed or between events. To determine the sequence of geologic events, several principles must be followed.

We often express time in hours or days, and 10 or 20 years certainly feels like a long time. Imagine if you needed to think about one million, million, or even several billion years. These exceptional lengths of time seem unbelievable, but they are exactly the spans of times that scientists use to describe the Earth. Have places like the Grand Canyon and the Mississippi River been around for all of those years, or were they formed more recently?
