Here's why:
* Felsic is a term derived from feldspar and silica, which are the two dominant minerals in these rocks.
* Feldspars are rich in aluminum, potassium, sodium, and calcium.
* Silica (SiO2) is a major component of the other minerals present, like quartz.
Some examples of felsic rocks include:
* Granite: A very common, coarse-grained rock with large crystals.
* Rhyolite: A fine-grained, volcanic equivalent of granite.
* Granodiorite: Similar to granite, but with a slightly higher percentage of plagioclase feldspar.
These rocks are typically light-colored because of the presence of light-colored minerals like quartz and feldspar. They are also relatively low in iron and magnesium, which are common in darker-colored mafic rocks.
