But in case of the Himalaya mountains was the speed of the plates just higher so more energy got 'into' the mountains. It includes Everest and K2, as well as other minor mountains and several glaciers. They formed long ago, and erosion has beveled them to their present low elevation Southwestern North America contains a large area called the Basin and Range province. You'll find some of the oldest rocks in the US in the Appalacians. This sediment was often subjected to intense heat and pressure as the mountains were uplifted again during the next orogeny. The Himalayas are the greatest mountain system in Asia and one of the planet's youngest mountain ranges, that extends for more than 2,400km across the nations of Bhutan, China, India, Nepal, and Pakistan.The term 'Himalaya' literally means the 'Abode of Snow' and has been derived from a combination of two Sanskrit words, 'Hima' which means 'snow' and 'Alaya .

The mountain range of the Himalaya, of which Everest is part, is to date growing as the Earth's continents are moving, pushing India further north and the Himalayas even higher. As for the Rocky Mountains, it is much younger than the Appalachian Mountains, but much older than the Himalayan Mountains, as the Rockies are no longer growing in elevation. The process drives magma to the continent's surface, leading to the creation of volcanic mountains, like Mount Fuji in Japan or Mount Saint Helens in Washington State. The ____ in California is the boundary between the North American and Pacific plates. Why are the Appalachian Mountains not as high as the Himalayan Mountains even though they were formed in the same way?
