Is mafic magma explosive?
Not usually. Mafic magma usually has a low gas content than felsic or intermediate magma, so eruptions are often effusive. Cinder cones primarily erupt mafic lava with a low level of explosivity. Explosive eruptions can also occur if the magma comes in contact with groundwater.
Why are eruptions of mafic magma rather quiet?
The explosive force of violent eruptions is driven by gas trapped in the magma under pressure. Mafic magma often has a relatively low gas content and so usually erupts in a non-explosive or mildly explosive.
Magma that is low in silica and produces nonexplosive eruptions is called?
That would be basaltic magma.
Do the most violent volcanoes spew mafic?
No. The most violent eruptions involve felsic magma.
Magma that is relatively thin dark colored and low in silica?
A low silica magma is called a "mafic" magma.
Does mafic magma explode?
Mafic magma can be involced in both explosive and non-explosive eruptions.
Magma that is low in silica and produces nonexplosive eruptions?
Low viscosity mafic magma.

What do quiet lava eruptions generally result from?
Volcanic eruptions are always caused by magma. This applies if the eruption is quiet or explosive, or whether the magma is felsic or mafic.

That would be basaltic magma.

What eruption is worse mafic or silicic?
Eruptions involcing silicic or felsic magma are generally the worst. Eruptions of mafic material are usually effusive or only mildly explosive, producing cinders or lava flows. Eruptions of felsic material often produce large ash clouds and deadly pyroclastic flows.
Is felsic magma eruptive?
Not usually. Because it is so viscous, felsic magma does not erupt as easily as mafic magma. While eruptions of felsic magma do occur, most felsic rocks are intrusive, meaning they solidify underground.
This type of magma has low silica content?
There are three types of magma that contains silica. Basaltic Magma has 50 percent silica, Andesitic Magma has 60 percent silica, and Granitic Magma has 70 percent silica.
The types of magma?
Felsic, intermediate, mafic and ultra mafic are the four broad types of magma.
