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.

Suppose a volcano that is about to erupt contains mafic magma. The mafic magma has a very low silica content. what types of igneous rocks will the volcano most likely form?
basalt
What type of magma does cotopaxi have?
blue the cotopaxi volcano has red magma when turned to rock. it also has a high silica content
How does silica content affect igenous rocks?
It determines high silica or low silica. It will determine if it is sticky or not, or if it flows fast or slow. *high in silica~Sticky, and slow. Will not flow easily. *low in silica~Fact, not sticky. Will flow easily.
What type of lava is erupted from Mount Kilimanjaro?
Mt. Fuji is Japan's highest mountain. The lava that comes out of this volcano is silica-poor lava that is very thick and chunky.
Should a kid be able to play with silica jell?
No, while colorless silica gel is non-toxic, the dopants used as color moisture indicator in silica gel (such as cobalt (II) chloride) are carcinogens and are quite toxic.
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.
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 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.
