  2. OBJECTIVES 1 In addition to lava, volcanoes erupt large quantities of gases and solid particles such as ash. 2 Even though every volcano is unique, most can be classified as one of only a few basic types. 3 The shapes of several types of volcanoes are determined by their eruptive style. 4 Some volcanoes erupt explosively, whereas others erupt rather quietly and pose little danger to humans. 5 Eruptions in some areas yield vast, flat-lying sheets of lava or layers of ash and other particles rather than volcanoes. 6 Geologists use several methods to monitor volcanoes in an effort to predict future eruptions. 7 A semiquantitative scale is used to express the size of an eruption. 8 Most volcanism takes place in well defined belts at or near divergent and convergent plate boundaries. 9 The few active volcanoes far from any plate boundary probably result from localized melting of rock at hot spots.
