Composite volcanoes are layered with various igneous rocks and minerals of different types, size, and density. Basaltic lava flows, ash, rhyolite, sulfur, and pumice are all examples of materials used to build these structures.
Like nearly all magma it is composed primarily of molten silicate minerals with variable amounts of dissolved gasses. In addition to silica (silicon dioxide), common substances also include magnesium oxide, iron oxide, calcium oxide, sodium oxide, and potassium oxide. There is more variability of composition in the magma of composite volcanoes than there is in in other types, primarily in the relative proportions of these oxides.
Rock.
^^Erupted material, to be more specific. Hardened lava, ash, rock, etc.
Composite volcanoes are composed of irregular layers of ash, welded tuff, lava flows, lava domes, and pumice. In some cases these may be mixed together in landslide debris.
The materials in a composite volcano are: overlapping layers of tephra, volcanic ash, and lava.
They are made up of layers of lava, volcanic ash, cinders, and other materials.

What do composite volcanoes shoot out?
they shoot out magma
What type of magma does a composite volcano have?
Composite volcanoes typically have andesitic magma, which is intermediate in composition between felsic and mafic magmas. This type of magma is more viscous than mafic magma, leading to explosive eruptions and the buildup of lava and ash layers that form the characteristic steep-sided cone shape of composite volcanoes.
What are three facts about composite volcanoes?
Composite volcanoes are also known as stratovolcanoes, characterized by steep-sided cones due to alternating layers of lava flows, ash, and volcanic rocks. These volcanoes often erupt explosively due to the high viscosity of the magma, which can trap gases and lead to pressure buildup. Some of the world's most famous volcanoes, like Mount St. Helens and Mount Fuji, are composite volcanoes.
What type of magma is found on composite volcano?
The average composition of magma in a composite volcano is andesitic. Composite volcanoes are highly variable though. They can erupt anything from basalt to rhyolite.
Do composite volcanoes have high or low silica?
Composite volcanoes are often associated with moderate to high silica contestant, though in reality, the magma composition will vary over time.
What do composite volcanoes shoot out?
they shoot out magma
What are three names of composite volcanoes?
the magma is so hot

Where are volcanoes made?
All volcanoes are made of gas and magma.
Why are there different shaped volcanoes?
Different shaped volcanoes occur because of the way the magma flows. Three types of volcanoes are shield, composite, and caldera.
Do composite volcanoes have high or low silica?
Composite volcanoes are often associated with moderate to high silica contestant, though in reality, the magma composition will vary over time.
What types of volcanoes are created when andesitic magma erupts?
Andesitic magma will result in the formation of a stratovolcano, also called a composite volcano.
Does a composite volcano have a high gas content?
Yes. Composite volcanoes often have a high gas content in their magma, which is why they often erupt explosively.
What is the type of lava in the composite volcanoes?
Composite volcanoes typically erupt with a mixture of lava types, including both viscous lava (andesitic or rhyolitic) that can lead to explosive eruptions, as well as more fluid lava (basaltic) that can flow long distances. This combination of lava types is what gives composite volcanoes their steep-sided profile.
