Volcanic is composed of clay to sand-sized particles of rock and volcanic glass. This material is expelled from a volcano during a violent eruption. Steam buildup in a volcano causes violent eruptions that shred the surrounding rock into small, ash particles. An information card with details on the rocks formation, mineral content, characteristics and uses is included.
