Continental crust is basically ________,whereas oceanic crust is basically ________.
A)thin thick
B)basalt granite

Question

Quizplus · Accepted Answer

Continental crust is primarily composed of granite, which is a felsic rock that is less dense than the mafic rock basalt that makes up the oceanic crust. Therefore, oceanic crust is primarily composed of basalt, which is denser and thinner than the continental crust. Sima refers to the composition of the oceanic crust and is primarily made up of basalt and gabbro, while sial refers to the composition of the continental crust and is primarily made up of granite and other felsic rocks. Silica and sodium are not necessarily the primary components of either crust, so options E and D are not the best choices.
