These volcanoes are made of many layers of rubble, old lava, and dome rocks. They grow to be higher than 3000 meters above their bases. They are created from multiple eruptions that occur over many years. Composite cones can continue growing with each eruption until their slopes collapse. Examples include Mount St. Helens, Mount Rainier, Mount Fuji, and Klyuchevskoy Valcano (Russia).
