What type of magma containing a lot silica and water vapor?
Felsic magma
What do both silica and water do to magma?
Silica is silicon dioxide. Is is perhaps the most common compound on earth. In magma the amount of silica is key in determining the viscosity. More silica leads to a more viscous magma.
What determines whether a volcano will erupt violently or quietly?
if a volcano is high in silica, it will be explosive. If its low in silica, it will be quiet. Two important things that determine whether an eruption will be explosive or quiet: # The amount of water vapor and other gases that are trapped in the magma. # If the magma is basaltic or grantic.
What type of magma has a high silica content?
rhyolitic magma has a lot of silica and water vapors... thanks for asking answers.com ;)
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.
What type of magma containing a lot silica and water vapor?
Felsic magma
What is the type of magma contain a lot of silica and water vapor is?
The three types of magma, named for the rock they form are basaltic, rhyolitic and andesitic. Rhyolitic magma is rich in silica and water vapor.

What is Silica rich thick magma called?
The three types of magma, named for the rock they form are basaltic, rhyolitic and andesitic. Rhyolitic magma is rich in silica and water vapor.
What is the relationship between the amount of gases in magma and the explosiveness a volcanic eruption?
The more gases, water vapor and silica there is in magma the bigger the explosiveness of a volcanic eruption.

What makes magma thicker?
If there is a high silica content in the magma, the eruption is usually more violent and explosive. Magma with a high silica content flows slower so pressure can build up and eventually erupt.
What can be made up of magma?
Silica, Water and carbon dioxide.

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.
Why is silica rich magma associated with explosive eruptions?
silica rich magma associated with explosive eruptions because it tends to trap water and gas bubbles :)
If a tall shield volcano has been built by many eruptions over thousands of years the magma that helped build the volcano contained?
a lot of silica and only a little water vapor
