The Nature Of Volcanoes

volanoes are mountains but they are very different from other mountains.The are formed by folding and crumpling but by uplift and erosion.A volcano is most commonly a conical hill or mountin built around a vent that connects with vreservoirs of molten rock below the surface of the earth.The term volcano also refers to the opening or vent through which the molte rock and associated gases are expelled.If so, an eruption begins, and the molten rock may pour from the vent as non-explosive lava flows,or if may shoot violently into the air as dense clouds of lava fragmemts.
