Geological time is a period of time covering the formation and development of the Earth from about 4.6 billion years ago to today. The geologic timescale or GTS is a system of chronological dating that relates geological strata to time. It is used by geologists and paleontologists to describe the timing and relationships of events that have occurred during the Earth's history.
