Here's why:

* Continental crust is the thicker, less dense layer of Earth's crust that makes up the continents.

* Granite is a common igneous rock found in the continental crust. It's formed from the slow cooling and crystallization of magma deep underground.

While granite is a significant component of the continental crust, it's not the only rock present. Other types of rocks like sedimentary and metamorphic rocks are also found in the continental crust.
