GEOLOGY

Detailed explanation-1: -A volcano mountain is formed by the surface eruption of magma from within the earth’s upper mantle. The magma that erupts to the surface and forms a lava flow that deposits ash. As the volcano continues to erupt, a new layer of lava is added to the surface, accumulating to form a mountain.

Detailed explanation-2: -Volcanoes are mountains but they are very different from other mountains; they are not formed by folding and crumpling or by uplift and erosion. Instead, volcanoes are built by the accumulation of their own eruptive products–lava, bombs (crusted over ash flows, and tephra (airborne ash and dust).

Detailed explanation-3: -A volcano is an opening in a planet or moon’s crust through which molten rock, hot gases, and other materials erupt. Volcanoes often form a hill or mountain as layers of rock and ash build up from repeated eruptions. Volcanoes are classified as active, dormant, or extinct.

Detailed explanation-4: -In contrast to the small fissure vents of the adjacent Devils Garden lava field, the Lava Mountain field consists of a shield volcano capped by the Lava Mountain pyroclastic cone complex that forms a prominent topographic high.

Detailed explanation-5: -Volcanic mountains: are formed as a result of volcanic activities on the surface of the Earth. The magma inside the Earth erupts out as lava through the cracks on the Earth’s surface. This cools down repeatedly to form volcanic mountains.
