How much silica is in a composite volcano?
A composite volcano has high silica because they are known to be explosive.
What two ingredients in magma affect the type of explosion and shape of a volcano?
water and mantle rock +++ More specifically, the silica proportion, plus water and gases from entrained wet, organic-rich sediment if the volcano is from subduction rather than a constructive plate margin. Increasing silica increases the magma's viscosity; the water and gas make it effervesce in the eruption.
What is silica content of a cinder cone volcano?
The silica content of the lava from a cinder cone volcano is typically low to moderate. This type of volcano erupts basaltic to andesitic lava, which contains lower silica levels compared to other types of volcanoes like stratovolcanoes.
What determines if a volcano erupts quietly or explosively?
silica levels

What is the shape of a volcano with low silica?
Shield 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.
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 silica content of a cinder cone volcano?
The silica content of the lava from a cinder cone volcano is typically low to moderate. This type of volcano erupts basaltic to andesitic lava, which contains lower silica levels compared to other types of volcanoes like stratovolcanoes.
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.
How does Silica determine if the volcano will be quiet or explosive?
Silica will determine if the volcano will be quiet or explosive by building itself up in the volcano pipe, plugging it up like a cork in a bottle and then exploding.
Why is magma with high levels of silica explosive?
The more silica the volcano has, the more the pressure is occurring and eventually it becomes so strong that the volcano erupts .
What type of volcano will form from a small volcano erupting with high amounts of silica?
penis
Does the shape of the volcano affect the directions the eruption travels?
i dont think so. So the answer is probably no.......
