Correct. Basaltic magma usually has a low gas content. Because of this, eruptions involving it are usually effusive or only mildly explosive.

Does basaltic magma have a lot of silica or very little?
Basaltic magma is low in silica compared to andesitic or granitic magma.
Is basaltic or andesitic magma hotter?
Basaltic magma is hotter than andesitic magma.
Is basaltic magma or granitic magma hotter?
Baslatic magma is hotter.
When equal amounts of a basaltic and granitic magma mix what is the resulting magma?
basaltic
What is shield volcanoes lava composed of?
TThe magma is composed of gas and is silica rich.

What is the difference between basaltic magma and silicic magma?
Granitic rocks are intrusive, which means they crystallized underground. Basaltic rocks are extrusive, meaning they crystallized above ground. Also, basaltic rocks are more mafic, and granitic rocks are more felsic.

TThe magma is composed of gas and is silica rich.
What color rocks does basaltic magma form?
Basaltic magma usually forms a black rock.
What are cinder cone magma chambers made up of?
bhill
Which would you expect to cause the greatest amount of contact metamorphism an intrusion of basaltic magma or an intrusion of rhyolitic magma?
Basaltic magma
What magma is the most abundant type erupted at oceanic spreading centers?
Basaltic magma.
If basalt is in lava is the volcano explosive?
No. The more basalt the quieter the eruption. Basalt is deep deep material, from down where there are few volatiles to make lava explosive.
