Answer:
volcanic eruption occurs when molten rock, ash and steam pour through a vent in the earth's crust.
Volcanoes are described as active (in eruption), dormant (not erupting at the present time), or extinct (having ceased eruption; no longer active). Some volcanoes explode. Others are slow-flowing fountains of lava, which is hot fluid rock.
Explanation:
volcanoes are vents or opening in the crust of the earth, connected by a conduit to an underlying magma chamber from which molten magma ,volcanic gases and steam are ejected.
Vocanicity is a process which involves the intrusion of magma in the earth's crust or extrusion of such molten material into the earth's surface.This process gives rise to volcanic eruptions
