  1. VOLCANOES BY: HANNAH DICKERSON

  2. SHIELD VOLCANOES , so named for their broad, shield-like profiles, are formed by eruption of low –viscosity lava that can flow a great distance from a vent . T hey generally do not explode catastrophically. Since low –viscosity magma is typically low in silica, shield volcanoes are more common in oceanic than continental settings. The Hawaiian volcanic chain is a series of Shield cones, and they are common in Iceland, as well. SHIELD VOLCANO

  3. Composite VOLCANOES is a steep-coned volcano that explosively emits gases, ash , pumice, and a small amount of stiff ,silica lava. This type of volcano can have eruptions accompanied by lakars—deadly mud flows. Most volcanoes on earth are of this type. Strato Volcanoes kill more people than any other type of volcanoes- this is because of their abundance on earth and their powerful mudflows. Examples are Krakatoa, in Washington State, USA.

  4. The Cinder Cone Volcano is shorter than other volcanoes. The Cinder Cone can shoot about 15 ft. high or more and when it comes down it makes a loud blat like ‘’BOOM.’’ It has very steep sides and usually has a small crater on top. These are the most common volcanoes on earth. This type of volcano can be hundred of miles across and many tens of thousands feet high. They only grow about thousand ft. and about a size of a hill.

  5. Shield volcanoes are taller than Cinder Cone volcanoes but Cinder Cone can shoot it’s lava higher. Shield volcanoes are so named for their broad. The Cinder Cone volcano has very steep sides and usually has a crate on top. Comparing Shield and Cinder Cone volcanoes
