Mafic magma is high in magnesium and iron, has a low silica content, and is less viscous compared to felsic magma. Mafic lava typically produces dark-colored rocks like basalt and is associated with oceanic crust. Mafic magma tends to erupt more quietly and flow more easily due to its lower viscosity.

This type of magma has low silica content?
Mafic magma has low silica content. It is usually rich in magnesium and iron, leading to its high density and fluid-like behavior. Mafic magmas tend to form basaltic rocks when they solidify.
Is the mt paricutin volcanoes magma mafic intermediate or felsic?
The magma of Paricutin volcano is classified as basaltic, which is a type of mafic magma. Mafic magmas are characterized by their low silica content and high levels of magnesium and iron.
Magma that is relatively thin dark colored and low in silica?
This type of magma is called mafic magma. It has a low viscosity due to its low silica content, allowing gases to escape easily. It typically contains high levels of iron and magnesium, making it darker in color.
Which is the most abundant in magma and has the greatest effect on its characteristics?
Silica is the most abundant component in magma and has the greatest effect on its characteristics. The amount of silica present determines the magma's viscosity, which in turn influences the explosiveness of volcanic eruptions.
Which set of characteristics best describes mafic magma?
Mafic magma is typically rich in magnesium and iron minerals, with a low silica content. It has a high temperature and low viscosity, allowing for it to flow easily. Mafic magmas commonly form basaltic rocks when they solidify.
The types of magma?
Felsic, intermediate, mafic and ultra mafic are the four broad types of 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.
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.
What are the two types of magma?
The two main types of magma are mafic and felsic.
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.
Magma that is low in silica and produces nonexplosive eruptions?
Low viscosity mafic magma.
Suppose a volcano that is about to erupt contains mafic magma. The mafic magma has a very low silica content. what types of igneous rocks will the volcano most likely form?
basalt
