Volcanic Cones and Eruptions

This site describes the three forms of volcanoes, which are cinder cones, the shield type and the composite or stratovolcano. The six major types of eruptions (Icelandic, Hawaiian, Strombolian Vulcanian, Pelean, and Plinian) are discussed. The site has diagrams and photographs to illustrate both the forms of the volcanoes and the types of eruptions and the relationship between them. The site also has links to goals, objectives, and materials and equipment for a hands-on activity dealing with the concept of viscosity. Educational levels: Middle school
