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.)

∙ 13y agoYes it does. That's way composite volcano's lava is so sticky and explosive.
Wiki User
∙ 12y agocomposite volcanoes are high in silica which means that they are very explosive

How much silica is in a composite volcano?
A composite volcano has high silica because they are known to be explosive.
What will happen if a volcano is high in silica?
It will be very explosive and also probably produce a cinder cone or composite volcano.
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.
What type of volcano has magma that contains large volumes of gases but not silica and water?
The most explosive type of volcano, which is the type that has water, is called a boiler volcano. All active volcanoes have magma, and emit carbon dioxide. Magma can contain silica.
Is laki a shield volcano or a composite volcano?
a shield volcano
How much silica is in a composite volcano?

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 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 .
Is katmai volcano a shield volcano?
No. It is a composite volcano.
Is laki a shield volcano or a composite volcano?
a shield volcano
Is arenal volcano a composite volcano or a cindercone volcano?
The arenal volcano is a cindercone volcano not a composite.
Is the Osorno volcano in Chile a shield or composite volcano?
it 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.
Is mount shasta a shield volcano a composite or a cinder cone volcano?
the mount hood volcano is strato (composite) volcano
