		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.
		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).
		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.

		In the Roman pantheon Vulcan was the son of Jupiter and Juno; in this role he was the counterpart of the Greek god Hephaestus, and later assumed many of the latter's characteristics.
		He normally was depicted as a grotesque figure with one leg shorter than the other, a deformity that resulted from being thrown from heaven by Jupiter while attempting to protect his mother from the god's wrath.
		Perhaps the most curious custom of Vulcan was the sacrifice of live fish, which were thrown onto fires lit on the banks of the Tiber in order to persuade the god to spear more vulnerable objects.

		Vulcan is the origin of the name we now give to those areas on Earth where magma comes forth as lava or pyroclastic flows, creating what we call “volcanoes.”
		There is a distinct difference in the kind emission from a volcano if the trapped gases can escape freely and easily (as in very fluid magma which is low in silica), or remain trapped and cannot escape easily (as in very thick magma which has a high silica content).
		All are volcanoes; all emit some type of material; all are formed from magma beneath the Earth; all are hills or mountains; all have vents or openings at the top.

		Volcanoes are built from layers of lava and tephra (particles of rock, solidified lava, and ash of all different sizes).
		Volcanoes are openings, or vents, in the surface of Earth where gases, lava and pyroclastic material are erupted.
		The volcano's height is reduced as it is eroded from the top, and the weight of the layers and layers of lava causes the volcano to subside (sink).

		A volcano is simply a vent at the surface of the earth through which lava and other volcanic materials are ejected from the Earth’s interior.
