Composite Volcano |

| Also called Stratovolcanoes, composite volcanoes
usually have very steep sides (Topinka, 2003). These volcanoes are
usually built by its own eruptive material including,
tephras, lava and
pyroclastic flows (VHP WWW Team, 2000). Because they are
built this way, they take hundreds of thousands of years.
Most composite volcanoes have a crater at the top that contains a central or a cluster of vents (Topinka, 2003). Lava flows through the cracks in the crater or flows through cracks on the side of the mountain (Topinka, 2003). The rocks typically found around these volcanoes are basalt, dacite, andesite, and rhyolite ( VHP WWW Team, 2000). All of these rock types minus basalt will create violent eruptions ( VHP WWW Team, 2000). Some of the more famous composite volcanoes are:
