geography/natural science
A volcano is a place on the Earth's surface (or any other planet's or moon's surface)
where molten rock, gases and pyroclastic debris erupt through the earth's crust.
Volcanoes vary quite a bit in their structure - some are cracks in the earth's crust where
lava erupts, and some are domes, shields, or mountain-like structures with a crater at
the summit. Magma is molten rock within the Earth's crust. When magma erupts
through the earth's surface it is called lava. Lava can be thick and slow-moving or thin
and fast-moving.
Rock also comes from volcanoes in other forms, including ash (finely powdered rock
that looks like dark smoke coming from the volcano), cinders (bits of fragmented
lava), and pumice (light-weight rock that is full of air bubbles and is formed in
explosive volcanic eruptions - this type of rock can float on water).
Volcanic eruptions can cause great damage and the loss of life and property.

The word volcano comes
from the Roman god of
fire, Vulcan.
Vulcan was said to have

melt and shape iron) on
Vulcano,
an active volcano on the
Lipari Islands in Italy.
