Want to know the basics in identifying the different varieties of volcanic rocks? If so, this video will help you understand the compositions of volcanic rocks, and more. • Volcanic rocks occur almost everywhere on the planet so it would be important for those who rock-hound, prospect, or for those who are interested with earth's geologic history, to be able to identify a volcanic rock. Volcanic rocks come in different varieties and compositions which can tell us what kind of volcano they may have come from and how explosive the eruptions may have been which can give us a glimpse of the geologic past. Volcanic and other igneous formations can provide important resources for us to use. • This is part of a series of videos that I am making where I teach geology.
