Question

Quizplus · Accepted Answer

Continental crust is primarily composed of granite, while oceanic crust is primarily composed of basalt. This difference in composition results in differences in thickness and density, with oceanic crust being thinner and denser than continental crust. The terms "sima" and "sial" refer to the composition of Earth's crust, with sima referring to the lower layer (which includes oceanic crust and the upper mantle) and sial referring to the upper layer (which includes continental crust).
