What else can I help you with?
Is felsic magma viscous?
Yes. Felsic magma is very viscous.
Where do mafic and felsic magma originate?
Felsic is a term that means that a rock contains types of silica. Fesic magma is magma that is high in silica particles and low in iron particles.
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.
What is moving Lava?
Felsic magma.
Does the presence of water raise the melting point of felsic magma?
No. Water lowers the melting point of magma, both mafic and felsic.
Is felsic magma viscous?
Yes. Felsic magma is very viscous.
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.
What are the similarities between a felsic magma andmafic magma?
Both consist of molten rock and minerals

What does magma with high silica content form?
When it cools and crystallizes into rock, the rock will be described as felsic igneous rock. Examples of felsic igneous rocks are granite, rhyolite, and pumice.
What type of magma does Mt.Tambora have?
felsic lava
What are the two types of magma?
The two main types of magma are mafic and felsic.
What type of magma containing a lot silica and water vapor?
Felsic magma
Why are eruption of mafic magma are quiet while eruption of Felsic magma are explosive?
Mafic magma, which is low in silica content, has a lower viscosity, allowing gases to escape easily during an eruption, resulting in quiet flows. In contrast, felsic magma is high in silica, making it more viscous and trapping gases within. When pressure builds up in felsic magma, it can lead to explosive eruptions as the trapped gases are released violently. This fundamental difference in composition and viscosity accounts for the contrasting eruption styles.
