Here's a breakdown:

* Felsic: This term refers to the composition of the rock. Felsic rocks are rich in silica (SiO2) and have a relatively high content of aluminum, potassium, sodium, and calcium.

* Igneous: This means the rock formed from the cooling and solidification of molten magma or lava.

* Granite: This is a common and well-known type of felsic igneous rock.

While granite is the dominant rock type in the continental crust, it's important to note that there are other types of rocks present as well, including:

* Sedimentary rocks: These form from the accumulation and cementation of sediments, such as sandstone, limestone, and shale.

* Metamorphic rocks: These form when existing rocks are transformed by heat and pressure, such as gneiss and schist.

However, the vast majority of the continental crust is made up of igneous rocks, with granite being the most prevalent type.
