What are the names of a plutonic solid?
Solid plutonic rocks are intrusive igneous rocks such as granite and gabbro.
What rock dominates Yosemite valley and is one of earth's most common igneous rocks?
Plutonic Ingenious Rocks.
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.
3 main groups of igneous rocks?
The three main groups of igneous rocks are intrusive (plutonic), extrusive (volcanic), and hypabyssal rocks. Intrusive rocks form below the Earth's surface from the slow cooling of magma. Extrusive rocks form on the Earth's surface from rapidly cooling lava. Hypabyssal rocks are intermediate rocks that form from magma that solidifies in the crust.
Is pegmatite felsic or mafic?
Pegmatite is classified as felsic due to its composition which is rich in silica and aluminum, containing minerals such as quartz, feldspar, and muscovite. Mafic rocks, on the other hand, have a higher content of iron and magnesium-rich minerals like pyroxene and olivine.
How was rock created?
By solidification of felsic plutonic bodies underground.
How was granite rock created?
By solidification of felsic plutonic bodies underground.
What are the names of a plutonic solid?
Solid plutonic rocks are intrusive igneous rocks such as granite and gabbro.
Are plutonic rocks igneous rocks that hardened on top of volcanoes?
No. Plutonic rocks are igneous rocks that hardened underground. Rocks that form on volcanoes are volcanic rocks.
What rock dominates Yosemite valley and is one of earth's most common igneous rocks?
Plutonic Ingenious Rocks.

What does the word felsic mean?
Felsic refers to rock rich in silica and aluminum content. It describes igneous rocks that are light in color and have high concentrations of minerals like quartz and feldspar. Felsic rocks are commonly found in continental crust.
Which pair of minerals is most likely to be found in felsic rock?
Quartz and feldspar are the most likely pair of minerals found in felsic rock. Felsic rocks are rich in silica, which forms minerals like quartz, and feldspar is another common mineral found in these rocks.
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 rocks are felsic?
Granite, rhyolite, and pegmatite are examples of felsic rocks. These rocks are light in color and have high silica content, making them rich in minerals like quartz and feldspar. Felsic rocks are associated with continental crust and are often found in areas with volcanic activity.
What is the difference between felsic intermediate and mafic igneous rocks?
Silica content increases from mafic to felsic, and Mg and Fe content decreases. These differences affect things such as viscosity, density and colour. Felsic magmas are the most viscous and least dense, and felsic rocks are the lightest in colour.
