Volcanic ash is also harmful when inhaled and  can damage the eyes and lungs. It can clog the engines of cars and  aircraft, and can bring down planes in flight. In some eruptions,  superheated clouds of ash and gas called pyroclastic flows race  down the slopes of a volcano.
Composite volcanoes are also called stratovolcanoes because of the alternating layers, or strata, of which they are made (Figure 8.22). The magma that creates stratovolcanoes tends to be more viscous, or thick. Viscous lava creates greater pressure which, in turn, tends to create explosive eruptions.esson Summary [edit]. 1  Composite cones, shield volcanoes, cinder cones and supervolcanoes are some of the types of volcanoes formed. 2  Composite cones are tall, cone shaped volcanoes that produce explosive eruptions. 3  Shield volcanoes form very large, gently sloped volcanoes with a wide base.
