These are the important parts of a Volcano
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.

Where the word VOLCANO comes from.
The word volcano comes from the Roman god of fire, Vulcan.
Vulcan was said to have had a forge (a place to melt and shape iron) on Vulcano,
an active volcano on the Lipari Islands in Italy.

The most active volcano in the continental USA is Mt. St. Helens, located in western Washington state.

erupted in 1707.
Krakatau Volcano, IndonesiaThis volcano erupted in 1883, when 36,000 individuals died.
24 square miles were blown to bits, and the eruption was heard 3,000 miles away.
