They're described as felsic igneous rocks.
Felsic rocks are light-colored igneous rocks rich in aluminum, potassium, silicon, and sodium. Examples include granite and rhyolite.
The Earth's crust is formed mainly from the elements aluminum, silicon and oxygen in the form of silicates & aluminum oxides and occurring as silicate rocks.Silicate minerals are abundant in all three rock types (igneous, metamorphic, and sedimentary) comprising the crust, but the crust is composed mainly of silicate rich igneous rock. The continental crust is composed of the lighter 'felsic' igneous rock (granitic in nature), higher in aluminum, sodium, and potassium; the oceanic crust is composed of the heavier, darker, 'mafic' igneous rock (largely basalt) which is higher in iron and magnesium than the continental crust.Crust composition: Oxygen, Silicon, Aluminum, Iron, in that order.Overall composition of the entire Earth: Iron, Oxygen, Silicon, Aluminum, in that order.Magnesium and Iron
The color of igneous rocks is determined by the minerals present in the rock. Dark-colored igneous rocks, such as basalt, contain minerals like pyroxene and olivine that are rich in iron and magnesium. Light-colored igneous rocks, such as granite, contain minerals like feldspar and quartz that are rich in silicon and aluminum. These mineral compositions influence the overall color of the rock.
Granite is not an element. It is a common type of igneous rock composed of minerals such as quartz, feldspar, and mica. These minerals are made up of elements like oxygen, silicon, aluminum, potassium, and others.
The Earth's crust contains oxygen, silicon, aluminum, calcium, iron, sodium, potassium, and magnesium. These elements are the major components of the minerals that make up the Earth's outermost layer.

No, potassium silicate and potassium aluminum silicate are two different compounds. Potassium silicate is a compound composed of potassium, silicon, and oxygen, while potassium aluminum silicate contains potassium, aluminum, silicon, and oxygen. They have different chemical compositions and properties.
KAlSi3O8 Potassium, aluminum, silicon, and oxygen.
The seven main elements commonly found in igneous rocks are silicon, oxygen, aluminum, iron, calcium, sodium, and potassium. These elements make up the minerals that compose igneous rocks and give them their characteristic properties.

No Igneous rock is consistently a compound - a mixture of elements. Although there are variations in composition, igneous rock is usually made up of roughly half oxygen, roughly one quarter silicon, and lesser, but significant, quantities of aluminum, calcium, sodium, potassium, and magnesium., with a sprinkling of other elements.

Lava is rich in minerals such as silicon, oxygen, aluminum, iron, magnesium, calcium, sodium, and potassium. The specific composition can vary depending on the type of volcano and where the lava originates from.
