Is Mt Etna a composite or a shield volcano?
Mt. Etna is a composite volcano, also known as a stratovolcano. It is characterized by its steep profile and explosive eruptions due to the presence of viscous magma rich in silica.
What type of volcano is most likely to form when magma is high in silica?
Lava high in silica (granitic lava) tends to be thick and viscous, so the volcano is likely to be composite rather than shield.
Is a composite volcano thick or runny?
A composite volcano, also known as a stratovolcano, typically has a thick and viscous lava flow due to its high silica content. This type of volcano tends to erupt explosively, producing a mixture of lava, ash, and volcanic rocks.
What type of volcano has magma that contains large volumes of gases but not silica and water?
A volcano with magma that contains large volumes of gases but not silica and water is typically a shield volcano. These volcanoes have low viscosity magma that allows gases to escape easily, resulting in relatively gentle eruptions characterized by lava flows.
Does a composite volcano have silica?
Yes it is high in silica because composite volcanoes are known for being explosive. Composite volcanoes, sometimes referred to as stratovolcanoes, one of Earth's most common type.They form by explosive eruptions of pyroclastic material followed by quieter outpourings of lava. This usually indicates high silica content. High silica makes for thicker magma that can clog up the vent from the volcanoe's last eruption. Which makes the next eruption far more explosive because the magma has to free its self out of the vent, and with tremendous force it succeeds sky rocketing billions of pieces of pyroclastic material out of its vent. (this is known as an explosive eruption.)
How much silica does a composite volcano have?
The silica content will vary from one volcano to the next and will even vary over time for a single volcano. On average, though, composite volcanoes erupt intermediate rocks that are 52-63% silica.

What is a volcano with high silica?
A volcano with high silica content is referred to as a stratovolcano or composite volcano. These volcanoes have highly viscous magma due to the high silica content, leading to explosive eruptions that can be violent and dangerous. Examples include Mt. St. Helens in the United States and Mt. Fuji in Japan.
How much damage does a complex volcano do?
not much, the volcano type that does he worst damage is the composite/strato volcano. The composite and strato volcano are the same types just different names.
What are the phases ofa volcano?
A volcano starts when a hole in the ground leeks magma. It lays out around the hole that started. It will take a while but eventually a big volcano will stand. It will be a composite volcano a shield volcano or a cinder cone volcano. The eruption wont always be explosive. It depends on the amount of silica in the lave. If it has alot of silica it will be explosive. If is low in silica it will ooz out. If you would like to know more go to www.newsdial.com Nature Natural Disasters .

What causes the difference between quiet and exploses eruptions?
It depends on how much silica is in the magma. If there is low-silica in the magma then the volcano will erupt quietly. If there is high-silica in the magma then the volcano will erupt explosively.
Is katmai volcano a shield volcano?
No. It is a composite volcano.
Is mount fuji a cinder cone volcano shield volcano or a composite volcano?
Mount Fuji is a composite volcano.

What does the amount of silica in a volcanos magma determine about its eruption?
If a volcano's magma is high in silica, the volcano will probably erupt explosively. If the magma is not high in silica, the volcano will probably erupt quietly.
