Explanation: 

Detailed explanation-1: -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-2: -Volcanic mountains are a special class of mountains. A volcano is a vent or opening through which magma, ash, gases, and water vapour are ejected out. Volcanic mountains consist of – Magma chamber, Vent, Lava, Crater, and pyroclastic flow.

Detailed explanation-3: -Volcanic mountains are formed due to volcanic activity. The molten lava, after cooling down, deposits around the volcano continuously to form a mountain.

Detailed explanation-4: -Volcanoes are vents, or openings in Earth’s crust, that release ash, gases and steam, and hot liquid rock called lava. When the lava cools and hardens, it forms into the cone-shaped mountain we think of as a volcano.

Detailed explanation-5: -Rocks at the base of A Mountain represent a lava flow, which is the earliest volcanic event evident at A Mountain.
