The Appalachian Mountains, which range from Canada down through the southeastern United States, started forming about 480 million years ago. In their prime they probably had peaks as high as those in the modern zone of continental collision stretching from the Himalayas in Asia to the Alps in Europe. Please refer to the appropriate style manual or other sources if you have any questions. The Himalayas are remarkable, because they are probably about tall as mountains are physically capable of being on earth. Sometimes an entire ocean closes as tectonic plates converge, causing blocks of thick continental crust to collide. The deep metamorphic rocks were brought back to the surface via two tectonic processes: thrust faulting and isostatic rebound. The effect is like a swimmer putting a beach ball under his or her bellythe swimmer will rise up considerably out of the water. Alongside that, the Rockies stretch across the country almost twice as long as the Appalachian Mountains (1,500 miles compared to 3,000 miles).
