Notes On Geological Time Scale Jan 11 2025 nbsp 0183 32 The Geologic Time Scale or Geological Time Scale GTS is a chronological framework that organizes Earth s history into various units based on geological and paleontological evidence It divides Earth s 4 6 billion year history into hierarchical units such as eons eras periods epochs and ages These divisions help scientists describe and interpret
The geologic time scale or geological time scale GTS is a representation of time based on the rock record of Earth It is a system of chronological dating that uses chronostratigraphy the process of relating strata to time and geochronology a scientific branch of geology that aims to determine the age of rocks The principal divisions of geological time are called eras Three eras are recognised the Plaeozoic ancient life the Mesozoic middle life and the Cenozoic recent life
