Composite volcanoes, also known as stratovolcanoes, primarily erupt magma that is andesitic in composition, which is intermediate between basaltic and rhyolitic magmas. This magma is characterized by higher viscosity due to its silica content, which leads to more explosive eruptions. The presence of volatiles, such as water and carbon dioxide, in the magma contributes to the formation of gas-rich eruptions, resulting in the characteristic steep-sided structure of composite volcanoes. Overall, the magma chemistry plays a critical role in determining the eruptive behavior and morphology of these volcanoes.
What else can I help you with?
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?
Multiple eruptions form composite volcanoes. Andesite magma is the most common type of magma that erupts from composite volcanoes. Composite volcanoes can grow so high that their slopes become unstable and collapse.
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?

What are three names of composite volcanoes?
the magma is so hot

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.
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 temperature is composite volcanoes?
Composite volcanoes, also known as stratovolcanoes, typically erupt magma that has a higher viscosity due to its higher silica content. The temperatures of the magma in these volcanoes generally range from about 800°C to 1,200°C (1,472°F to 2,192°F). This higher viscosity can lead to more explosive eruptions compared to other types of volcanoes.
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.
