Is silica intrusive or extrusive?
The terms intrusive and extrusive apply to the formation of igneous rocks. Silica is a chemical component of a wide variety of minerals found in many types of igneous, metamorphic, and sedimentary rock. All igneous rocks, both intrusive and extrusive, contain silica.
What sedimentary rock turns into the igneous rock basalt?
None. Basalt is formed by the rapid cooling of mafic (silica-poor) magma. It is not formed from sedimentary rock.
How would you classify a rock that has even amount of silica iron and magnesium?

What is a name of a sedimentary rock that becomes igneous?
metamorphic
What is rhyolitic composition?
It contains about 70% Silica(SiO2)Added:Rhyolite, a gost town town in South-Nevada, is named for rhyolite, an igneous rock composed of light-colored silicates, usually buff to pink and occasionally light gray. It belongs to the same rock class, felsic, as granite but is much less common.
An example of an igneous rock low in silica is granite?
Granite is actually high in silica, which is why it is considered a felsic igneous rock. An example of an igneous rock low in silica is basalt, which is mafic in composition and contains less silica than granite.
What color will igneous rock with high levels of silica be?
An igneous rock with a high level of silica will have a light color.
Which of the igneous rock types has the lowest silica content?
Ultramafic igneous rock contains the least silica.
What igneous rock family contains the highest proportion of silica?
Felsic igneous rock contains the highest proportion of silica. Granites are felsic igneous rocks.
Is silica an igneous rock?
No. Silica is not a rock; it is a component of many minerals found in all three rock types.
What is igneous rock color mainly determined by?
An igneous rock's color is mainly determined by its silica content.
How the silica content of Molten material affects the color of igneous rock's?
The more silica contained in a rock, the lighter in color it will be.
What is the name of an igneous rock with low silica content that flows easily?
Basalt is an igneous rock with low silica content that flows easily due to its fluid nature when erupted. It is commonly found in volcanic areas and is dark in color.
Would you expect a light gray igneous rock to be rich or poor in silica?
I would expect a light gray igneous rock to be rich in silica. Light gray color in igneous rocks is often associated with high silica content, which is typical of felsic or granitic compositions.
Is rhyolite an polymerization sedimentary rock?
No, rhyolite is a silica-rich volcanic or igneous rock.
What rock in the igneous family are medium colored and have no silica?
Igneous rocks that are medium colored and have no silica are called mafic rocks. They are mainly composed of magnesium and iron.
What is An igneous rock with a low silica content that flows easily?
Basalt.
