List Of Top Ten The World's Highest Mountains

The following is a list of the world's 100+ highest mountains per height above sea level (>7,200 metres / 23,622 feet), all of which are located in central and southern Asia. Only those summits are included that, by an objective measure, may be considered individual mountains as opposed to subsidiary peaks

Considerations

One of figures of topographic prominence: The prominence of a peak is the height of the peak’s summit above the lowest contour line encircling it and no higher summit. For example, vertical arrows show the topographic prominence of three peaks on an island. A dotted horizontal line links each peak (except the highest) to its key col.

The dividing line between a mountain with multiple peaks and separate mountains is not always clear (see also Highest unclimbed mountain). A popular and intuitive way to distinguish mountains from subsidiary peaks is by their height above the highest saddle connecting it to a higher summit, a measure called topographic prominence or re-ascent (the higher summit is called the "parent peak"). A common definition of a mountain is a summit with 300 m (980 ft) prominence. Alternatively, a relative prominence (prominence/height) is used (usually 7-8%) to reflect that in higher mountain ranges everything is on a larger scale. The table below lists the highest 100 summits with at least 500 m (1,640 ft) prominence, approximating a 7% relative prominence. A drawback of a prominence-based list is that it may exclude well-known or spectacular mountains that are connected via a high ridge to a taller summit, like the Eiger or Nuptse. A few such peaks and mountains with nearly sufficient prominence are included but not numbered in this list.
It is very unlikely that all given heights are correct to the nearest metre; indeed, the sea level is often problematic to define when a mountain is remote from the sea. Different sources often differ by many metres, and the heights given below may well differ from those elsewhere in this encyclopedia. As an extreme example, Ulugh Muztagh on the north Tibetan Plateau is often listed as 7,723 m (25,338 ft) to 7,754 m (25,440 ft), but appears to be only 6,973 m (22,877 ft) to 6,987 m (22,923 ft). Some mountains differ by > 100 m (330 ft) on different maps, while even very thorough current measurements of Mount Everest range from 8,840 m (29,003 ft) to 8,850 m (29,035 ft). These discrepancies serve to emphasize the uncertainties in the listed heights.
Though some parts of the world, especially the most mountainous parts, have never been thoroughly mapped, it is unlikely that any mountains this high have been overlooked, because synthetic aperture radar can and has been used to measure altitudes of most otherwise inaccessible places. Still, heights and/or prominences may be revised, so that the order of the list may change and even "new" mountains could enter the list over time. To be safe, the list has been extended to include all >7,200 m (23,622 ft) peaks.
The highest mountains above sea level are generally not the highest above the surrounding terrain. There is no precise definition of surrounding base, but Mount McKinley, Mount Kilimanjaro and Nanga Parbat are possible candidates for the tallest mountain on land by this measure. The bases of mountain islands are below sea level, and given this consideration Mauna Kea (4,207 m (13,802 ft) above sea level) is the world's tallest mountain and volcano, rising about 10,203 m (33,474 ft) from the Pacific Ocean floor. Ojos del Salado has the greatest rise on Earth— 13,420 m (44,029 ft) from the summit^{[citation needed]} to the bottom of the Atacama Trench about 560 km (350 mi) away, though most of this rise is not part of the mountain.
The highest mountains are also not generally the most voluminous. Mauna Loa (4,169 m (13,678 ft)) is the largest mountain on Earth in terms of base area (about 2,000 sq mi/5,200 km²) and volume (about 10,000 cu mi/42,000 km³), although, due to the intergrade of lava from Kilauea, Hualalai and Mauna Kea, the volume can only be estimated based on surface area and height of the edifice). Mt. Kilimanjaro is the largest non-shield volcano in terms of both base area (245 sq mi/635 km²) and volume (1,150 cu mi/4,793 km³). Mount Logan is the largest non-volcanic mountain in base area (120 sq mi/311 km²).
The highest mountains above sea level are also not those with peaks farthest from the centre of the Earth, because the figure of the Earth is not spherical. Sea level closer to the equator is several miles farther from the centre of the Earth. The summit of Chimborazo, Ecuador's tallest mountain, is usually considered to be the farthest point from the Earth's centre, although the southern summit of Peru's tallest mountain, Huascarán, is another contender.^[1] Both have elevations above sea level more than 2km less than that of Everest.

 Geographical distribution

Most mountains in the list are located in the Himalaya and Karakoram ranges. In fact, all 7,000 m (23,000 ft) peaks in the world are located in the centre of Asia (East Asia, Central Asia and South Asia) in a rectangle edged by Noshaq (7,492 m (24,580 ft)) on the Afghanistan-Pakistan border in the West, Peak Jengish Chokusu, (Tuōmù'ěr Fēng) (7,439 m (24,406 ft)) on the Kyrgyzstan - Xinjiang border to the North, Gongga Shan (Minya Konka) (7,556 m (24,790 ft)) in Sichuan to the East, and Kabru (7,412 m (24,318 ft)) on the Sikkim - Nepal border to the South.
The locations of the highest mountains are shown on the composite satellite image of High Asia below. The numbers refer to the ranking in the list. For clarity, lower peaks with labels overlapping higher peaks are left out of the main image. The boxed regions are those with the highest density of summits and are enlarged in two separate images to show all peaks.
