The document describes 3 types of volcanoes: cinder cone volcanoes which are steep and conical hills made of volcanic fragments that accumulate around and downwind from a vent; composite volcanoes also called stratovolcanoes which are formed from layers of lava and rock fragments that usually erupt explosively; and shield volcanoes which have shallow sloping sides and form from fluid lava flows that travel long distances across slight inclines. Examples of each type are provided.

3. What are Cinder cone volcanoes?A cinder cone or also known as scoria cone is a steep conical hill of volcanic fragments that accumulate around and downwind from a volcanic vent. Cinder cones range in size from tens to hundreds of meters tall. Cinder cones are made of pyroclastic materialCinder cone volcanoesHolocene cinder cone near Veyo,Utah.

5. Capulin volcano in New MexicoWhat are Composite volcanoesComposite volcanoes also called strato volcanoes, are formed by alternating layers of lava and rock fragments. Between eruptions they are often so quiet they seem extinct. To witness the start of a great eruption requires luck or very careful surveillance. Composite volcanoes usually erupt in an explosive way. Composite volcanoesTavurvur, an active stratovolcano near Rabaul in Papua New Guinea

7. Redoubt volcanoWhat are Shield volcanoesA shield volcano is a volcano with shallow-sloping sides. Shield volcanoes normally form from fluid lava flows that can travel long distances across slight inclines.
