Partial melting of the lower continental crust produces a silicic magma that eventually solidifies into granite or rhyolite.

Question

Quizplus · Accepted Answer

This statement is true. Continental crust is mainly composed of felsic rocks, which are rich in silica and aluminum. When subjected to high heat and pressure, partial melting of the lower continental crust can produce a silicic magma that has high viscosity and is more prone to explosive eruptions. This magma eventually solidifies into granite or rhyolite, which are common rocks in continental crust.
