 continents were once joined up in a huge
super-continent called Pangaea. About 200 million years ago, Pangaea began
to break up, and the various pieces have been drifting around the world
ever since.
 About
200 million years ago, Pangaea began to break up.
As the
plates of the earth's crust moved Pangea broke apart forming two large
land masses, Laurasia in the north and Gondwana in the
south. Eventually these land masses also broke apart to form the
continents we recognize today. North America and Eurasia were formed from
Laurasia while the remaining continents formed from Gondwana. The movement
of the continents continues today, with North America getting farther away
from Europe each year.
