It also built up a meltwater lake that Pedersen et al. define as “a pillow-dominated flat-topped tuya without a lava cap”. [7] H. Björnsson explains that though the mountain is crossed by many faults and a graben, so that it looks like a complex formation, its origin is in a single eruption. [6]
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 ]
Mount Everest, Earth's highest mountain. A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock.Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (980 ft) above the surrounding land.
A volcano needs a reservoir of molten magma (e.g. a magma chamber), a conduit to allow magma to rise through the crust, and a vent to allow the magma to escape above the surface as lava. The erupted volcanic material (lava and tephra) that is deposited around the vent is known as a volcanic edifice, typically a volcanic cone or mountain. [2] [22]
Girnar is an ancient hill in Junagadh, Gujarat, India.It is one of the holiest pilgrimages for Jains, where the 22nd Tirthaṅkar, Lord Neminath attained omniscience, and later nirvana along with other five hundred and thirty three enlightened sages.

A subglacial volcano, also known as a glaciovolcano, is a volcanic form produced by subglacial eruptions or eruptions beneath the surface of a glacier or ice sheet which is then melted into a lake by ...
Magmatism is the emplacement of magma within and at the surface of the outer layers of a terrestrial planet, which solidifies as igneous rocks. It does so through magmatic activity or igneous activity, the production, intrusion and extrusion of magma or lava. Volcanism is the surface expression of magmatism.
Swargarohini (IAST: svargārohiṇī) is a mountain massif in the Saraswati (Bandarpunch) Range of the Garhwal Himalaya. It lies in the Uttarkashi District of the northern Indian state of Uttarakhand, west of the Gangotri group of peaks. It comprises four separate peaks, the main peak Swargarohini I is the subject of this article.
