Inside a volcano
The diagram representation above shows what a basic volcano looks like.
- The magma chamber:
This is the area with a massive collection of magma below the earth’s crust from which magma flows out.
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 openings 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.
