Why are felsic rocks melted by mafic magmas but mafic rocks are not melted by felsic magmas?
Felsic rocks have a lower melting point than mafic rocks and felsic magma has a lower temperature. In other words, felsic magma is not hot enough to melt mafic rock while mafic magma is hot enough to melt felsic rock.
Does the presence of water raise the melting point of felsic magma?
No. Water lowers the melting point of magma, both mafic and felsic.
Does magma having a silica content of 50 percent is more mafic than one having a silica content of 70 percent?
No, magma with a silica content of 50 percent is more felsic, while magma with a silica content of 70 percent is more mafic. Silica content is inversely proportional to magma's mafic or felsic classification.
Does Krakatoa have felsic magma or mafic?
Krakatoa volcano typically has mafic magma, which is low in silica content and high in magnesium and iron. This type of magma tends to be more fluid and can lead to explosive eruptions due to the rapid release of gases.
Is the mt paricutin volcanoes magma mafic intermediate or felsic?
Like most cinder cones Paricutin was fed by mafic magma.
Why are felsic rocks melted by mafic magmas but mafic rocks are not melted by felsic magmas?
Felsic rocks have a lower melting point than mafic rocks and felsic magma has a lower temperature. In other words, felsic magma is not hot enough to melt mafic rock while mafic magma is hot enough to melt felsic rock.
The types of magma?
Felsic, intermediate, mafic and ultra mafic are the four broad types of magma.
What are the two types of magma?
The two main types of magma are mafic and felsic.
What are some different types of magma?
Mafic intermediate and Felsic
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.
Does the presence of water raise the melting point of felsic magma?
No. Water lowers the melting point of magma, both mafic and felsic.
Does magma having a silica content of 50 percent is more mafic than one having a silica content of 70 percent?

Is the mt paricutin volcanoes magma mafic intermediate or felsic?
Like most cinder cones Paricutin was fed by mafic magma.
Mafic mineral low or high density?
Mafic minerals generally have a relatively high density compared to felsic minerals. This is because mafic minerals are rich in iron and magnesium, which are denser elements. As a result, rocks rich in mafic minerals like basalt and gabbro tend to be heavier and denser than rocks composed of felsic minerals like granite.
Does the mantle have mafic magma or felsic magma in it?
The mantle primarily contains mafic magma, which is rich in iron and magnesium. Felsic magma, which is rich in silica, is more commonly found in areas associated with continental crust or in volcanic arcs.
Do the most violent volcanoes spew mafic?
No. The most violent eruptions involve felsic magma.
