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
What else can I help you with?
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.
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.
Did AA lava form composite volcanoes?
No, composite volcanoes are typically formed from explosive eruptions caused by viscous lava containing high amounts of silica. A'a lava, on the other hand, is characterized by its rough and blocky texture and typically forms shield volcanoes or cinder cones.
What are tyes of volcanoes?
There are three main types of volcanoes: shield volcanoes, cinder cone volcanoes, and stratovolcanoes. Shield volcanoes have gentle slopes and are formed by thin lava flows. Cinder cone volcanoes are made up of pyroclastic material, such as ash and rock fragments. Stratovolcanoes are large, steep-sided volcanoes that erupt a mixture of lava flows and explosive eruptions.
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.

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 scientist test volcanoes?
So they can warn people and evacuate them if one is going to erupt.
Why do you not hear or know about most volcanoes?
Because They erupt so u can't hear them
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.
What type of volcano doesn't erupt?
A volcano that doesn't erupt is typically classified as a "dormant" or "extinct" volcano. Dormant volcanoes have the potential to erupt in the future but have not done so for a significant period of time, while extinct volcanoes are not expected to erupt again. Examples include the Eiffel Tower in France and the ancient volcanoes found in the Hawaiian Islands that have not shown any activity for thousands of years.
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 .
