Question

Quizplus · Accepted Answer

Oceanic crust is denser than continental crust and is composed primarily of basalt. This is because oceanic crust is formed from the solidification of mafic magma, which is denser than the felsic magma that forms continental crust. Continental crust is primarily composed of granite, which is a felsic rock that is less dense than basalt.
