The light colored rock that makes up most of the continental crust is granite.

Here's why:

* Composition: Granite is a felsic igneous rock, meaning it's rich in feldspar and quartz, which are light-colored minerals. This gives granite its characteristic light color.

* Formation: Granite forms deep within the Earth's crust through the slow cooling and crystallization of magma.

* Abundance: While other rocks like basalt are found in the continental crust, granite is the most abundant type.
