What makes the Rocky Mountains cordillera? The prevailing hypothesis for the Rockies birth, called flat-slab subduction, says that the Pacific oceanic plate dove underneath the North American plate at an unusually shallow angle. The relentless if very slow movement of the plates underlying the Pacific Ocean towards the continental mass of North and South America has created a huge topographic rise the American Cordillera (or mountain chain). The Andes contain the highest peaks in the Western Hemisphere. All other trademarks and copyrights are the property of their respective owners.
