Figure 6-8The Supercontinent Pangaea (a) The present continents are pieces of what was once a larger, united body called Pangaea. (b) Geologists believe that Pangaea must have first split into two smaller supercontinents, which they call Laurasia and Gondwana. (c) These bodies later separated into the continents of today. Gondwana split into Africa, South America, Australia, and Antarctica, while Laurasia divided to become North America and Eurasia.
