A. lava from a composite volcano-andesite B. eruption column-tephra C. pyroclastic flow-scoria D. volcanic-derived mudflow-breccia with angular fragments. An extinct volcano is one which has erupted thousands of years ago and there’s no possibility of eruption. ... or through a massive explosive volcanic eruption. The type of eruption, whether explosive or nonexplosive, also affects the overall shape. Furthermore, these different classifications often correlate.

About 1000 to 1500 years ago, an explosive eruption produced pyroclastic flows. A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater.For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has … Strombolian eruptions involve moderate bursts of expanding gases that eject clots of incandescent lava in cyclical or nearly continuous small eruptions. In this case, however, fluid lava flows from a volcano’s summit and radial fissures to form shield volcanoes, which are quite large and have gentle slopes.
