Types Of Volcanoes Download Free Pdf Volcano Types Of Volcanic Learn about volcanoes, their formation, types, eruptive materials, and the effects of volcanic eruptions on earth. middle school level presentation. Volcanoes are formed along two types of plate boundary: destructive and constructive. volcanoes occur where molten rock (magma) comes to the surface of the earth. the magma rises to the surface through cracks in the crust called vents. Volcanic activity is classified by how often a volcano erupts. a volcano may be active, intermittent, dormant, or extinct. active volcanoes erupt constantly. intermittent volcanoes erupt fairly regularly. dormant volcanoes are inactive, but not long enough to determine whether they will erupt again or not. Unlike stratovolcanoes that are composed of viscous lavas and ash, shield volcanoes are made of fluid basalt lavas flows, that flow much further, thus giving them their characteristic shield like shape.
