Let's review. Volcanoes are vents in the earth's crust through which lava, rock fragments, hot vapor and gases are ejected. There are different types of volcanoes based on their size, shape, composition and eruptive style. Composite cone volcanoes are cone-shaped volcanoes composed of layers of lava, ash and rock debris.
An igneous rock is formed by the cooling and crystallization of molten rock. The term igneous is derived from ignius, the Latin word for fire. Scientists have divided igneous rocks into two broad categories based on where the molten rock solidified. Volcanic rocks (also called extrusive igneous rocks) include all the products resulting from eruptions of lava (flows and fragmented debris called pyroclasts).
