A high landform which stretches over an area, and usually in the form of a cone, is a mountain.
You can define a mountain by: elevation, relief, volume, steepness, continuity and spacing.The mountain definition include:- elevation over base at least 8,202 ft (2,500 m)- elevation over base between min 4,921 ft (1,500 m) and max 8,202 ft (2,500 m) and a slope bigger than 2 degrees- height over base - min 1,000 m (3,281 ft) and max 1,500 m (4,921 ft) with a slope bigger than 5 degrees- local with radius 22,966 ft (7,000 m) and height greater 984 ft (300 m)The mountain covers the earth in this proportions: 24% of entire Earth, 22% of America, 64% of Asia, 25% of Europe, 3 % of Africa and 17% of Australia.Depending upon the mountain characteristics, how the mountains are formed and the geological process, there are five main types of mountains:- Fold Mountains: this is the most common type of mountains, example: the Alps (Europe), Himalayas (Asia), they are formed due to the impact of two plates.- Fault-Block Mountains: example: in North America the Sierra Nevada mountains, there are 2 types of block mountains: tilted (one steep side with an exposed scarp and one gently sloping side) and lifted (two steep sides), are formed when large areas of bedrock slide along faults (creating vertical displacements) in the Earth's crust.- Volcanic Mountains: the best example is the Mount Fuji from Japan, formed when the volcano erupted and the magma came up and sat down at the earth surface layer upon layer.- Dome Mountains: are formed when magma rise a layer of the earth and cools down there without erupting (this make the core of the mountain), example: Navajo Mountain in Utah.- Plateau Mountains: formed by erosion and called pseudo mountains, example: the Catskill Mountains in New York.Orography is the study of the relief and formation of mountains, including hills and other area of land of high terrain.Mountain news and articles:Mountain definitionDefinition of mountain http://www.articlesbase.com/hobbies-articles/mountains-all-about-2789170.html
