Exploring Plate Motion Concepts

The video tutorial covers the article 'Steno and the Shark' from a plate motion lesson. It discusses how Nicholas Steno's study of shark teeth led to significant insights in geology, particularly in understanding fossils and rock layers. Steno's work introduced the concept of relative dating, which helps determine the age of rock layers. The video also explains the geologic time scale, breaking Earth's history into eons, eras, and periods.
