Crust describes the outermost shell of a terrestrial planet. Earth’s crust is relatively thin, just 40-kilometers (25-miles) deep. Earth's crust can be divided into two types: continental and oceanic. Which of these does NOT explain how these two types of crust differ?
A Continental crust is thicker than oceanic crust.
B Continental crust is less dense than oceanic crust.
C Continental crust granitic composition: oceanic crust basalt and gabbro.
D Continental crust enriched with Fe and Mg: oceanic enriched with Al and Si.

Explanation: Continental crust is felsic (granitic), enriched in silica (Si) and aluminum (Al) and is less dense and thicker. Oceanic crust is mafic (basalt/gabbro), richer in iron (Fe) and magnesium (Mg) and is thinner and denser.
