The Continental The Continental DivideDivide

The Continental The Continental DivideDivide

The Continental Divide in the Americas is the line that divides the flow of water between the Pacific Ocean and Atlantic Ocean. Rain or snow that drains on the east side of the Continental Divide flows toward the Atlantic Ocean while precipitation on the west side drains and flows toward the Pacific Ocean. (However, some rivers empty into the desert and don't end up in the oceans.)
