Yes they do.
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.
Felsic rocks are usually intrusive, meaning they form below the Earth's surface from magma that cools and solidifies slowly. This slow cooling allows minerals such as quartz and feldspar to crystallize and form coarse-grained textures commonly seen in intrusive rocks like granite.
mafic because it is-dark colored. Ultramafic - no light colored mineral which means it it attracts most heat from a volcano taking it longer to cool down from the lighter, in between substance known as felsic :D
Mafic igneous rocks typically contain minerals like olivine, pyroxene, and amphibole which are not commonly found in felsic igneous rocks. These minerals have higher concentrations of iron and magnesium and form at higher temperatures as compared to the minerals present in felsic rocks.
As igneous rocks become more felsic, their density generally decreases. Felsic rocks, which are rich in silica and contain lighter minerals such as quartz and feldspar, tend to have lower overall densities compared to mafic rocks that are richer in iron and magnesium. This is due to the higher proportion of lighter elements in felsic compositions, leading to a less dense rock structure. Consequently, the trend shows that as the mineral composition shifts toward more felsic characteristics, the density diminishes.

The word felsic is used to describe igneous rocks that are rich in silica and alkali feldspar. Such rocks tend to be light in color and have a lower density than other igneous rocks.
Felsic rocks are primarily composed of minerals like quartz, feldspar, and muscovite, while mafic rocks contain minerals such as olivine, pyroxene, and plagioclase. Felsic rocks have lighter-colored minerals and lower density compared to mafic rocks, which have darker-colored minerals and higher density.
Felsic lavas cool to form igneous rocks when they solidify and harden after being erupted from a volcano. The cooling process can happen either on the surface of the Earth or underground, and the slow cooling allows minerals to crystallize and form the igneous rock.
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.
Felsic rocks like granite are light-colored igneous rocks with a lower density than basaltic rocks due to their silica-rich composition. Their lower density is a result of having a higher proportion of quartz and feldspar minerals, which are lighter than the minerals found in basalt.
Not all rocks do cool and crystallize, your question is meaningless.

No, pumice is an example of a felsic igneous rock. Mafic rocks, like basalt, have lower silica content and higher iron and magnesium content compared to felsic rocks, like pumice, which have higher silica content and lower iron and magnesium content.
False. Light colored rocks with lower densities typically form from felsic magma, which has a higher silica content compared to basaltic magma. Felsic rocks include granite and rhyolite, which are commonly light in color and less dense.
