The Barberton Greenstone Belt in South Africa is estimated at 3.4-3.6 billion years old, and generally regarded as the world's oldest mountains. Their age is indisputedly older than anything in North America (the Appalachians / Blach Hills / Porcupines / Smokies etc) and only Western Australia lays a possible claim.
Mount Everest is called the world's highest mountain because it has the highest elevation above sea level . We could also say that it has the highest altitude. The peak of Mount Everest is 8,850 meters (29,035 feet) above sea level. No other mountain on Earth has a higher altitude.himborazo in Ecuador has an altitude of 6,310 meters (20,703 feet). Mount Everest has a higher altitude and Mauna Kea is taller. However, Chimborazo has the distinction of being the highest mountain above Earth's center. This is because Earth is not a sphere-it is an oblate spheroid.
