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.
Igneous rock (derived from the Latin word ignis meaning fire) is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava.Igneous rock may form with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.This magma can be derived from partial melts of pre-existing rocks in either a planet's mantle or crust.ntrusive igneous rocks are formed from magma that cools and solidifies within the crust of a planet, surrounded by pre-existing rock (called country rock); the magma cools slowly and, as a result, these rocks are coarse grained. The mineral grains in such rocks can generally be identified with the naked eye.
