What is the magma composition causes the most violent volcanic eruptions explain?

Felsic magmas produce the most violent reputations. This is because felsic magmas are the most viscous and thus can hold the most gasses. These trapped gases can expand explosively when they reach lower pressure near the surface.

Only the most violent volcanic eruption feature?
Only the most violent volcanic eruptions feature a pyroclastic flow.
What shape is built up from numerous violent volcanic eruptions?
cone
What causes the most violent eruptions in volcanoes?
high viscosity in magma composition.
What do only the most violent volcanic eruptions feature?
The most violent volcanic eruptions are found in destructive/convergent plate boundaries. 80% of the world's active volcanoes are found occur along destructive boundaries. Acid-lava and composite volcanoes also cause the most violent eruptions as the lava is viscous and the opening of the volcano is sometimes blocked by hardened lava, causing a huge massive explosion during the eruption.
Can scientists predict volcanic eruptions?
Yes, scientists can predict volcanic eruptions, but only to a certain extent of accuracy. One method is to use earthquakes. Earthquakes usually increase and become more violent before a volcanic eruption

Are volcanic eruptions in the ring of fire generally quiet or violent?
Volcanic eruptions in the Ring of Fire are generally violent, though not all eruptions are. Kilauea is an example of a volcano that has relatively quiet eruptions, but it is a deep mantle hotspot volcano not part of the ring of fire system and its lava is low in water content. In general the volcanoes in the Ring of Fire that have violent eruptions including Mt. St. Helens, Mt. Pinatubo, Krakatoa, and Mt. Mazama because their lava is high in water content which increases the possibility of steam explosions during an eruption.
These volcanic eruption types is the least violent?
Which of these volcanic eruption types is the least violent? B. Hawaiian A. Pelean B. Hawaiian C. Strombolian D. Plinian
Why are some volcanic eruptions gentle and others violent and why do scientist make a distinction?
Because it all depends on what type of volcano it is, if it is a shield volcano low and flat it's eruptions will be gentle. But if it is a cone volcano tall and steep it's eruptions will be very violent.
Moderate to violent eruptions throwing volcanic ash cinders and lava high in to the air?
Cinder Cone Volcano
Do volcanoes have a scale magnitude?
Volcanoes don't, but volcanic eruptions do. Volcanic eruptions are rated by Colcanic Explosivity Index or VEI based on the volcume of material ejected. It ranges from VEI-0 for the non-explosive eruption of lava to VEI-8 for the most violent eruptions of supervolcanoes.
What type of magma causes violent erpuptions?
Highly viscous felsic magma causes the most violent volcanic eruptions.
What kind of magmas produce violent volcanic eruptions?
Those that are rich in iron and magnesium.
