What does a continental divide represent?

The "Continental Divide"separates the Atlantic and Pacific watersheds.The continental divide (on any continent) is the place where rain falling on one side would go to the ocean on one side (the Pacific Ocean in the case of North America) and rain on the other side would eventually make its way to the other side of the continent (the Atlantic Ocean). Canada has a somewhat unique continental divide, as water has three destinations: the Pacific, the Atlantic, and the Arctic oceans. There are actually six continental divides in North America.
