They are created from multiple structures during different kinds of eruptions. Composite volcanoes are made of cinders, ash, and lava. Cinders and ash pile on top of each other, lava flows on top of the ash, where it cools and hardens, and then the process repeats. Some examples are Mt Versuvius and Mt Stromboli in Italy

∙ 11y agoThey are called composite volcanoes because they are composed of a variety of materials including lava flows, ash, and pumice.

∙ 7y agoComposite volcanoes are often fed by highly viscous gas-rich magma. As the magma approaches the surface the gas is released and expands violently.

Did AA lava form composite volcanoes?
No, generally not. Most composite volcanoes erupt more viscous, high-silica material than what would form a'a. So block lava would be more common.
Why do you think that it is a struggle to come to terms with volcanoes?
Scientists study Volcanoes so, they can predict when they will erupt.
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.
How many volcanoes are erupting every day in the US?
There is no fixed length to an erruption, it varies from volcano to volcano. a volcano can erupt in days or more than its depend on its manner .
Why do shield volcanoes erupt frequently but rarely cause human disasters?
Shield volcanoes erupt lava with a low silica content. There are less dissolved gases and a lower viscocity fluid, so less gas is produced and it takes less pressure to erupt.

No, generally not. Most composite volcanoes erupt more viscous, high-silica material than what would form a'a. So block lava would be more common.
Are volcano's mountains?
Not all volcanoes are mountains though most do form mountains. Some volcanoes form as simple fissures in the ground. There is a so-called supervolcano in Yellowstone that, does not take the form of a mountain. Kimberlite volcanoes also erupt too violently to form mountains.

Why do some volcanoes erupt in under water?
because they were formed under the sea so when they erupt the can form tsunamis
What are three names of composite volcanoes?
the magma is so hot
Why do shield volcanoes erupt frequently but rarely cause human disasters?
Shield volcanoes erupt lava with a low silica content. There are less dissolved gases and a lower viscocity fluid, so less gas is produced and it takes less pressure to erupt.
What are four landforms created from lava and ash?
If you are talking about underwater volcanoes, than i have a answer. So, when underwater volcanoes erupt it MIGHT be able to create a island like Hawaii. Hawaii was made because of an eruption underwater.
Why do you not hear or know about most volcanoes?
Because They erupt so u can't hear them
Why do scientist test volcanoes?
So they can warn people and evacuate them if one is going to erupt.
What are tyes of volcanoes?
volcanoes are so awesome! There are 3 types. Composite,cindercone,and shield.Well,that is really all
