what is Geological Time Scale
Answers
The geologic time scale (GTS) is a system of chronological dating that relates geological strata (stratigraphy) to time. It is used by geologists, paleontologists, and other Earth scientists to describe the timing and relationships of events that have occurred during Earth's history. The table of geologic time spans, presented here, agree with the nomenclature, dates and standard color codes set forth by the International Commission on Stratigraphy (ICS).
Answer:
(1) Geological time scale is the arrangement of major divisions of geological time into eras, periods and epochs on the time scale.
(2) This division ls based on the study of fossilized organisms obtained from he different strata of the earth.
(3) The characterisitic significant events that occurred in the organization of organisms helped the geologisis to understand ihe geological time scale.
(4) The major divisions of geological time are called eras.
(5) The eras are divided into periods and the periods into epochs.
(6) By studying fossils in the carth crust, the evolutionary changes in the organisms have been traced out.
