Mountain formation occurs due to a variety of geological processes associated with large-scale movements of the Earth's crust (tectonic plates). [1] Folding , faulting , volcanic activity , igneous intrusion and metamorphism can all be parts of the orogenic process of mountain building. [ 2 ]
A mountain range or hill range is a series of mountains or hills arranged 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]
Main chain of the Alps. The main chain of the Alps, also called the Alpine divide is the central line of mountains that forms the drainage divide of the range. Main chains of mountain ranges are traditionally designated in this way, and generally include the highest peaks of a range.
The Alps are often divided into Eastern, Central and Western Alps, even though the boundaries between these subdivisions are arbitrary.The division between the Eastern and Central Alps is approximately the line between St. Margrethen, Chur and Sondrio; the division between the Central and Western Alps is unclear (Pfiffner 2009, p. 25).
While smaller groups within the Alps may be easily defined by the passes on either side, defining larger units can be problematic. A traditional divide exists between the Western Alps and the Eastern Alps, which uses the Splügen Pass (Italian: Passo dello Spluga) on the Swiss-Italian border, together with the Rhine to the north and Lake Como in the south as the defining features.
Richard Chorley (1927–2002), a key contributor to the quantitative revolution and the use of systems theory in geography. Sir Nicholas Shackleton (1937–2006), who demonstrated that oscillations in climate over the past few million years could be correlated with variations in the orbital and positional relationship between the Earth and the Sun.

The central core of the Great Dividing Range is dotted with hundreds of peaks and is surrounded by many smaller mountain ranges or spurs, canyons, valleys and plains of regional significance. Some of the major plains include the High Plains of South-Eastern Australia, the Southern Highlands, the Central Highlands and Bogong High Plains of
