Does low silica magma cause explosive volcanic eruptions?
Not usually. Explosive eruptions are more often to magma with high or moderate silica levels.
What type of magma will produce explosive eruptions?
Felsic magmas that are high in silica content and are highly viscous produce explosive eruptions.
Does Hawaii experience effusive or explosive eruptions?
Occasionally, yes. Most of Kilauea's eruptions are effusive, however.
How does magma composition and the resulting eruption affect the form of a volcano?
If the composition of the magma is high in silica, the eruption will be explosive. The Eruption of Mt. St. Helens was an explosive eruption. If the composition of the magma is low in silica, it will produce a quiet eruption. The eruption(s) of Mt. Kilauea are quiet eruptions.
How do differences in magma affect volcanic eruptions?
If the magma has a high water content, then the volcano will most likely have an explosive eruption. Also, vocanoes can have explosive eruptions if the magma contains a large percentage of silica. Hope this helps!

Do silica-rich magma cause explosive eruptions?
yes

How can the composition of magma affect the way volcano erupts?
If the composition of the magma is high in silica, the eruption will be explosive. The Eruption of Mt. St. Helens was an explosive eruption. If the composition of the magma is low in silica, it will produce a quiet eruption. The eruption(s) of Mt. Kilauea are quiet eruptions.

Which set of magma conditions produces the most explosive eruptions?
Magma is a hot fluid from deep within the Earth's crust. The set of magma conditions that produce the most explosive eruptions are high viscosity and the presence of dissolved gases.
Does thin magma cause explosive eruptions?
No, quiet eruptions.
What are two reasons that magma with a high silica content tend to cause explosive eruptions?
Magma with a high silica content tend to cause explosive eruptions because it has a stiff consistency and blocks the vents. When magma pushes from behind it more pressure happens which means the eruption will be explosive. It also prevents gas and water vapor from getting out. The gases will expand until it explodes.
An explosive eruption occurs if magma is?
Eruptions are explosive if the magma is viscous and has a high gas content.
Does mafic magma explode?
Mafic magma can be involced in both explosive and non-explosive eruptions.
