Lesson: The Geologic Time Scale Geology

Start Practising

In this lesson, we will learn how to recognize the geologic time scale and how geological time is classified and divided up using dating methods such as radiometric dating and index fossils.

Lesson Plan

Students will be able to

  • recognize the geologic time scale and describe its divisions,
  • explain the methods used to determine the divisions of the geologic time scale, including radiometric dating and index fossils for each period,
  • understand why the complete geologic time scale is not seen in any one location on Earth.
