Continental Drift

Continental Divide: The Breakup of Pangaea | Exploratorium

This interactive activity adapted from the Exploratorium presents evidence that supports the theory of plate tectonics, which explains how and when continents have shifted position over time. Geological and biological evidence have played important roles in forming the theory, and in return the theory has provided answers to some challenging questions.

This media asset was adapted from the Exploratorium's Continental Divide: The Breakup of Pangaea.
