Dynamic music pumps up viewers as they learn about intrusive and extrusive igneous rocks. Presentation slides include a graphic depiction of magma below Earth's surface , photographs of lava exploding and flowing, and close-ups of igneous rock samples. Each slide contains a few sentences of information that will educate viewers about how igneous rocks are formed. Consider using this presentation along with a rock cycle video and presentations on the other rock types, links to which are provided at the bottom of the webpage.
