What kind of plate boundary runs across Iceland convergent? Click to see full answer. The diagram shows the most-likely explanation, which is that the subducted slab did not sink as rapidly as normal for a while, and friction along its upper surface rumpled the overlying rocks of North America to raise the Rockies. As the plates continue to collide, mountains will get taller and taller. Rocky Mountain Plate The Rocky Mountains are part of a series of mountains called the North American Cordillera.
