PANGAEA

The Continental Drift Theory explains the existence of a supercontinent before its pieces drifted apart and resulted to smaller continents. This idea was presented in 1912 by geophysicist and meteorologist Alfred Wegener.

The supercontinent was named Pangaea ("all the Earth") by Wegener.

This is an illustration of supercontinent Pangaea.

This is an illustration that represents Pangaea before and after.

The seven continents of the world are Africa, Antarctica, Asia, Australia, Europe, North America, and South America.

The continents fit together, and are like puzzle pieces of Pangaea.
