Volcanoes are formed when magma from within the Earth's upper mantle works its way to the surface. At the surface, it erupts to form lava flows and ash deposits. Over time as the volcano continues to erupt, it will get bigger and bigger.
Volcano. A volcano is a fissure or vent through which molten rock material, or magma, and gases from the interior of the earth erupt on to its surface, and the landform, which is produced as a result of this eruption.he processes that create volcanoes and other volcanic structures are called volcanism.
