North American Oceans and Mountains
Oceans lap the shores of the continent--the Pacific on the west and the Atlantic on the east. Mountain ranges separate both coasts of the continent from the middle. The very old Appalachian Mountains follow the eastern coast. On the western coast, the newer and taller Alaska Range and Sierra Madre Occidental rise above the land. Slightly inland stand the Rocky Mountains and the Sierra Madre Oriental.
