The magma chamber: This is the area with massive collection of magma below the earth’s crust from which magma flows out.
Crater: After an eruption, the tip or top of the volcano tends to get blown off, leaving a small depression at the top of it.
Main vent: This is the main exit point (opening or outlet) in a weak zone where molten magma is released to the surface.
Secondary vents: These are other smaller vents or opening through which ash and gases and lava escape.
Ashes, clouds and cinders: As the eruption continues, ashes and gases are discharged into the air, which is carried further by wind action.
Layers of ash and lava: The walls of a volcano are usually made up of solidified layers of lava and dust.
