The Rocky Mountains were formed when the large plates that form the surface of the earth moved around and collided with each other. It is thought that this occurred over 120 million years ago. The plates are moving still, albeit very slowly. You can find more information here: http://www.mountainnature.com/geology/platetectonics.htm
