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.

Why is magma that contains little silica less to erupt explosively?
Magma with less silica is thinner and runnier.Therfore, gases can move out of the magma easily.
Why is magma that contains little silica less likely to erupt explosively?
Magma with less silica is thinner and runnier.Therfore, gases can move out of the magma easily.
How does magma with lots of silica trap gases?
High silica is sticky and highly viscous, acting to impede the movement and escape of gases.
Why volumes of gases are converted into STP conditions and then compares?
Since volumes of gases change with temperature and pressure, a standard value of temperature and pressuure is chosen to which gas volumes are referred. Hence volumes of gases are converted into S.T.P. conditions and then compared easily.
Why does high silica magma tend to form volcanic domes with steep sides?
because the volcano's vent gets plugged, gases cannot escape and pressure build up.
Why do you say that a volcano erupt violently?
It actually depends on the amount of silica and other gases trapped in the magma.

What is a holocene volcano?
A holocene volcano is a volcano that is made up of several different particles of holocene (Chemical gases) that come from basaltic silica or granitic silica. A quiet flow makes a slow and steady amount of various amounts of holocene, while the granitic flow, the explosive flow, makes a fast amount. High viscosity and low viscosity are also parts and particles of placements of holocene.
Do gases escape from a low silica magma easier than it does a high silica magma?
yes
What determines if a volcano will have a violent eruption or a quite eruption?
What makes a volcano erupt violently or quietly actually depends on the type of magma inside of it. The magma in volcanoes have different compositons from each other. magmas are sometimes classified by their silica content, which determines how viscus they are (how fluid they are). The more silica the lava has in it, the more thick it is. In very fluid or basaltic lavas, the silica content is around 50%. On the other end of the scale are granitic magmas that have a very high silica content (90%). when a volcano containing fluid magma erupts, the gas within the lava is easily relased, resulting in lava fountains like hawai'i's Kilewea. In a volcano that contains thick, granitic magma, the gases within the lava are trapt inside of it until the eruption lets the gases out, resulting in a violent, distructive explosion such as Mt St Helens.
What two ingredients in magma affects 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.
