Does silica or water have the greater effect on the eruptive force of the volcano?

Water gas a greater influence. Regardless of the amount of silica present, an eruption cannot be explosive if there is no gas present, and the chief gas is water vapor. Magma that is high in silica but low in gas content will be slowly extruded to form a lava dome or a very thick lava flow.

How much silica is in a composite volcano?
A composite volcano has high silica because they are known to be explosive.
What is silica content of a cinder cone volcano?
High silica levels are in cinder cone volcano's
Is the lava from a shield volcano thick or thin?
silica content
What determines if a volcano erupts quietly or explosively?
silica levels
Does low silica mean shield volcano?
a shield volcano is a low dome shaped volcano so i'd say yes
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 is the shape of a volcano with low silica?
Shield Volcano
What is silica content of a cinder cone volcano?
High silica levels are in cinder cone volcano's
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 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
Is the lava from a shield volcano thick or thin?
silica content
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 .
