Which magma contains small amounts of silica and has a low what?
Andesitic
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 silica is in a composite volcano?
A composite volcano has high silica because they are known to be explosive.
What type of volcano is characterized by low silica magma and relatively nonviolent eruptions?
flood basalt, lava dome, and shield volcanoes do.
What is silica content of a cinder cone volcano?
High silica levels are in cinder cone volcano's
What type of volcano will form from a small volcano erupting with high amounts of silica?
penis
Which magma contains small amounts of silica and has a low what?
Andesitic
What is the relationship between silica or water content of magma and materials ejected from an volcano?
The concentration of silica and water content in magma influence the force with which it is ejected from a volcano. The higher the levels of water and other gasses as well as the more silica it contains, the more explosive the eruption will be.

How much silica is in a composite volcano?
A composite volcano has high silica because they are known to be explosive.
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.
What type of volcano is characterized by low silica magma and relatively nonviolent eruptions?
flood basalt, lava dome, and shield volcanoes do.
What is the shape of a volcano with low silica?
Shield Volcano
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 is silica content of a cinder cone volcano?
High silica levels are in cinder cone volcano's
Is scoria rich in silica?
No. Scoria is relatively silica poor.
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.
