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.
Thirty of the worldâs highest mountains are in the Himalaya. The summit of Mount Everest, at 29,035 feet (8,850 meters), is the highest point on Earth. The tallest mountain measured from top to bottom is Mauna Kea, an inactive volcano on the island of Hawaii in the Pacific Ocean.ther types of mountains form when stresses within and between the tectonic plates lead to cracking and faulting of the Earth's surface, which forces blocks of rock up and down. Examples of fault-block mountains include the Sierra Nevada in California and Nevada, the Tetons in Wyoming, and the Harz Mountains in Germany.
