The Info List - Mountain Range

--- Advertisement ---

A mountain range or hill range is a series of mountains or hills ranged in a line and connected by high ground. A mountain system or mountain belt is a group of mountain ranges with similarity in form, structure and alignment that have arisen from the same cause, usually an orogeny.[1] Mountain
ranges are formed by a variety of geological processes, but most of the significant ones on Earth
are the result of plate tectonics. Mountain
ranges are also found on many planetary mass objects in the Solar System
Solar System
and are likely a feature of most terrestrial planets. Mountain
ranges are usually segmented by highlands or mountain passes and valleys. Individual mountains within the same mountain range do not necessarily have the same geologic structure or petrology. They may be a mix of different orogenic expressions and terranes, for example thrust sheets, uplifted blocks, fold mountains, and volcanic landforms resulting in a variety of rock types.

Most geologically young mountain ranges on the Earth's land surface are associated with either the Pacific Ring of Fire

or the Alpide Belt. The Pacific Ring of Fire
Pacific Ring of Fire
includes the Andes
of South America, extends through the North American Cordillera

along the Pacific Coast, the Aleutian Range, on through Kamchatka, Japan, Taiwan, the Philippines, Papua New Guinea, to New Zealand.[2] The Andes
is 7,000 kilometres (4,350 mi) long and is often considered the world's longest mountain system.[3] The Alpide belt includes Indonesia
and southeast Asia, through the Himalaya, and ends in the Alps, Spain
and Atlas Mountains.[4] The belt also includes other European and Asian mountain ranges. The Himalayas contain the highest mountains in the world, including Mount Everest, which is 8,848 metres (29,029 ft) high and traverses the border between China
and Nepal.[5]

The Ocean Ridge, the world's longest mountain range (chain)

ranges outside these two systems include the Arctic Cordillera, the Urals, the Appalachians, the Scandinavian Mountains, the Altai Mountains
Altai Mountains
and the Hijaz Mountains. If the definition of a mountain range is stretched to include underwater mountains, then the Ocean Ridges form the longest continuous mountain system on Earth, with a length of 65,000 kilometres (40,400 mi).[6] Divisions and categories[edit] The mountain systems of the earth are characterized by a tree structure, where mountain ranges can contain sub-ranges. The sub-range relationship is often expressed as a parent-child relationship. For example, the White Mountains of New Hampshire and the Blue Ridge Mountains are sub-ranges of the Appalachian Mountains. Equivalently, the Appalachians are the parent of the White Mountains and Blue Ridge Mountains, and the White Mountains and the Blue Ridge Mountains
Blue Ridge Mountains
are children of the Appalachians. The parent-child expression extends to the sub-ranges themselves: the Sandwich Range
Sandwich Range
and the Presidential Range
Presidential Range
are children of the White Mountains, while the Presidential Range
Presidential Range
is parent to the Northern Presidential Range
Presidential Range
and Southern Presidential Range. Climate[edit]

The position of mountains influences climate, such as rain or snow. When air masses move up and over mountains, the air cools producing orographic precipitation (rain or snow). As the air descends on the leeward side, it warms again (in accordance with the adiabatic lapse rate) and is drier, having been stripped of much of its moisture. Often, a rain shadow will affect the leeward side of a range. Erosion[edit] Mountain
ranges are constantly subjected to erosional forces which work to tear them down. The basins adjacent to an eroding mountain range are then filled with sediments which are buried and turned into sedimentary rock. Erosion
is at work while the mountains are being uplifted until the mountains are reduced to low hills and plains. The early Cenozoic
uplift of the Rocky Mountains
Rocky Mountains
of Colorado provides an example. As the uplift was occurring some 10,000 feet (3,000 m) of mostly Mesozoic
sedimentary strata were removed by erosion over the core of the mountain range and spread as sand and clays across the Great Plains
Great Plains
to the east.[7] This mass of rock was removed as the range was actively undergoing uplift. The removal of such a mass from the core of the range most likely caused further uplift as the region adjusted isostatically in response to the removed weight. Rivers are traditionally believed to be the principal cause of mountain range erosion, by cutting into bedrock and transporting sediment. Computer simulation has shown that as mountain belts change from tectonically active to inactive, the rate of erosion drops because there are fewer abrasive particles in the water and fewer landslides.[8] Extraterrestrial "Montes"[edit]

Saturn's moon Titan[9] and Pluto,[10] in particular exhibit large mountain ranges in chains composed mainly of ices rather than rock. Examples include the Mithrim Montes

and Doom Mons on Titan, and Norgay Montes

also exhibit rocky mountain ranges, such as Maxwell Montes
