When a volcano erupts it can throw solid materialsinto the air, like particles of ash and large rocks,
called volcanic bombs.
The volcanic cone is formed by many layers of ash and lava.
Lava is magma that rises to the Earth’s surfaceand flows out of a volcano.
The crater is the opening where lava and solid materials
come out of a volcano.
The conduit is the vertical shaft that carries magma to
the surface.
The magma chamberis a large pool of magma under a
volcano near the earth surface.
