About the Lesson

In this lesson, students will use a simulation to explore the relationship between continental drift and seafloor spreading.

 As a result, students will…

  • Measure the distance between South America and Africa over a 120 million year time span.
  • Understand how the age of the ocean floor relates to its distance from a mid-ocean ridge.
