Some of the Earth's grandest mountains are composite volcanoes--sometimes called stratovolcanoes.They are typically steep-sided, symmetrical cones of large dimension built of alternating layers of lava flows, volcanic ash, cinders, blocks, and bombs and may rise as much as 8,000 feet above their bases.
