What kind of rocks make up make up of the igneous rock Where can you find such rocks?

Igneous is derived from the Latin word for fire (ignis), which is very appropriate since igneous rock can be created by volcanic action. It is the oldest form of rock and can be found where ever the earth's crust has been opened by volcanoes or earthquakes, allowing molten rock to seep to the surface. (Think: Islands!) Four types of igneous rock exist: 1. Obsidian: extrusive (forced to the surface) igneous rock that is actually glass and not minerals. Sharp edges, smooth surface. 2. Pumice: another extrusive igneous rock but, unlike obsidian, this volcanic rock was pitted by millions of tiny air bubbles. It, too, is glass and not minerals... and it can float! 3. Granite: very hard igneous rock formed deep within the earth and composed of feldspar and quartz. This is intrusive igneous rock because it is formed below the surface of the earth. 4. Scoria: extrusive, glass, with a pitted surface much like pumice. Scoria is more dense and has a darker color with much larger pits.
